MHTML is a very interesting format since it's used both for emails but
also for archived webpages. Some scraping projects want to store pages
in disk to process them later, mhtml is perfect for that use case.
This is heavily inspired from the beautifulsoup html loader, but
extracting the html part from the mhtml file.

# beautifulsoup get_text kwargs in WebBaseLoader
- Description: this PR introduces an optional `bs_get_text_kwargs`
parameter to `WebBaseLoader` constructor. It can be used to pass kwargs
to the downstream BeautifulSoup.get_text call. The most common usage
might be to pass a custom text separator, as seen also in
`BSHTMLLoader`.

### Just corrected a small inconsistency on a doc page (not exactly a

This PR targets the `API Reference` documentation.
- Several classes and functions missed `docstrings`. These docstrings
were created.
- In several places this

# Description
It adds a new initialization param in `WikipediaLoader` so we can
override the `doc_content_chars_max` param used in `WikipediaAPIWrapper`
under the hood, e.g:
```python
from langchain.document_loaders import WikipediaLoader
# doc_content_chars_max is the new init param
loader = WikipediaLoader(query="python", doc_content_chars_max=90000)
```
## Decisions
`doc_content_chars_max` default value will be 4000, because it's the
current value

Fix a typo in
`langchain/experimental/plan_and_execute/planners/base.py`, by changing
"Given input, decided what to do." to "Given input, decide what to do."
This is in the docstring for functions running LLM chains which shall
create a plan, "decided" does not make any sense in this context.
This link for the notebook of OpenLLM is not migrated to the new format

vertex Ai chat is broken right now. That is because context is in params

#6610](https://github.com/hwchase17/langchain/issues/6610)
We may want to process load all URLs under a root directory.
For example, let's look at the [LangChain JS
documentation](https://js.langchain.com/docs/).
This has many interesting child pages that we may want to read in bulk.
Of course, the `WebBaseLoader` can load a list of pages.
But, the challenge is traversing the tree of child pages and actually
assembling that list!
We do this using the `RecusiveUrlLoader`.
This also gives us the flexibility to exclude some children (e.g., the
`api` directory with > 800 child pages).
## Goal
We want to ensure consistency across vectordbs:
1/ add `delete` by ID method to the base vectorstore class
2/ ensure `add_texts` performs `upsert` with ID optionally passed
## Testing
- [x] Pinecone: notebook test w/ `langchain_test` vectorstore.
- [x] Chroma: Review by @jeffchuber, notebook test w/ in memory
vectorstore.
- [x] Supabase: Review by @copple, notebook test w/ `langchain_test`
table.
- [x] Weaviate: Notebook test w/ `langchain_test` index.
- [x] Elastic: Revied by @vestal. Notebook test w/ `langchain_test`
table.
- [ ] Redis: Asked for review from owner of recent `delete` method

Fixes#5456
This PR removes the `callbacks` argument from a tool's schema when
creating a `Tool` or `StructuredTool` with the `from_function` method
and `infer_schema` is set to `True`. The `callbacks` argument is now
removed in the `create_schema_from_function` and `_get_filtered_args`
methods. As suggested by @vowelparrot, this fix provides a
straightforward solution that minimally affects the existing
implementation.
A test was added to verify that this change enables the expected use of
`Tool` and `StructuredTool` when using a `CallbackManager` and inferring
the tool's schema.

Many cities have open data portals for events like crime, traffic, etc.
Socrata provides an API for many, including SF (e.g., see
[here](https://dev.socrata.com/foundry/data.sfgov.org/tmnf-yvry)).
This is a new data loader for city data that uses Socrata API.
