Add user_context to AmazonKendraRetriever (#8869)
### Description 

Now, we can pass information like a JWT token using user_context:  

```python
self.retriever = AmazonKendraRetriever(index_id=kendraIndexId, user_context={"Token": jwt_token})
```

- [x] `make lint`
- [x] `make format`
- [x] `make test`

Also tested by pip installing in my own project, and it allows access
through the token.

Add: USearch Vector Store (#8835)
## Description

I am excited to propose an integration with USearch, a lightweight
vector-search engine available for both Python and JavaScript, among
other languages.

## Dependencies

It introduces a new PyPi dependency - `usearch`. I am unsure if it must
be added to the Poetry file, as this would make the PR too clunky.
Please let me know.

Make json output parser handle newlines inside markdown code blocks (#8682)
Update to #8528

Newlines and other special characters within markdown code blocks
returned as `action_input` should be handled correctly (in particular,
unescaped `"` => `\"` and `\n` => `\\n`) so they don't break JSON
parsing.

when encountering error during fetch return "" in web_base.py (#8753)
when e.g. downloading a sitemap with a malformed url (e.g.
"ttp://example.com/index.html" with the h omitted at the beginning of
the url), this will ensure that the sitemap download does not crash, but
just emits a warning. (maybe should be optional with e.g. a
`skip_faulty_urls:bool=True` parameter, but this was the most
straightforward fix)

Introduce Nebula LLM to LangChain (#8876)
## Description

This PR adds Nebula to the available LLMs in LangChain.

Nebula is an LLM focused on conversation understanding and enables users
to extract conversation insights from video, audio, text, and chat-based
conversations. These conversations can occur between any mix of human or
AI participants.

Examples of some questions you could ask Nebula from a given
conversation are:
- What could be the customer’s pain points based on the conversation?
- What sales opportunities can be identified from this conversation?
- What best practices can be derived from this conversation for future
customer interactions?

You can read more about Nebula here:

https://symbl.ai/blog/extract-insights-symbl-ai-generative-ai-recall-ai-meetings/

#### Integration Test 

An integration test is added, but it requires network access. Since
Nebula is fully managed like OpenAI, network access is required to
exercise the integration test.

#### Linting

- [x] make lint
- [x] make test (TODO: there seems to be a failure in another
non-related test??? Need to check on this.)
- [x] make format

### Dependencies

No new dependencies were introduced.

### Twitter handle

If you have any questions, please let me know.

Add support for Xata as a vector store (#8822)
This adds support for [Xata](https://xata.io) (data platform based on
Postgres) as a vector store. We have recently added [Xata to
Langchain.js](https://github.com/hwchase17/langchainjs/pull/2125) and
would love to have the equivalent in the Python project as well.

The PR includes integration tests and a Jupyter notebook as docs. Please
let me know if anything else would be needed or helpful.

I have added the xata python SDK as an optional dependency.

## To run the integration tests

You will need to create a DB in xata (see the docs), then run something
like:

```
OPENAI_API_KEY=sk-... XATA_API_KEY=xau_... XATA_DB_URL='https://....xata.sh/db/langchain'  poetry run pytest tests/integration_tests/vectorstores/test_xata.py
```

feat(llms): add support for vLLM (#8806)
Hello langchain maintainers, 
this PR aims at integrating
[vllm](https://vllm.readthedocs.io/en/latest/#) into langchain. This PR
closes #8729.

This feature clearly depends on `vllm`, but I've seen other models
supported here depend on packages that are not included in the
pyproject.toml (e.g. `gpt4all`, `text-generation`) so I thought it was
the case for this as well.

Async Recursive URL loader (#8502)
Description: This PR improves the function of recursive_url_loader, such
as limiting the depth of the access, and customizable extractors(from
the raw webpage to the text of the Document object), so that users can
use other tools to extract the webpage. This PR also includes the
document and test for the new loader.
Old PR closed due to project structure change. #7756

Because socket requests are not allowed, the old unit test was removed.
Issue: N/A
Dependencies: asyncio, aiohttp
Tag maintainer: @rlancemartin
Twitter handle: @ Zend_Nihility

Feature faiss delete (#8135)
<!-- Thank you for contributing to LangChain!

Replace this comment with:
- Description: docstore had two main method: add and search, however,
dealing with docstore sometimes requires deleting an entry from
docstore. So I have added a simple delete method that deletes items from
docstore. Additionally, I have added the delete method to faiss
vectorstore for the very same reason.
