core[minor]: Image prompt template (#14263) 
Builds on Bagatur's (#13227). See unit test for example usage (below)

```python
def test_chat_tmpl_from_messages_multipart_image() -> None:
    base64_image = "abcd123"
    other_base64_image = "abcd123"
    template = ChatPromptTemplate.from_messages(
        [
            ("system", "You are an AI assistant named {name}."),
            (
                "human",

                    {"type": "text", "text": "What's in this image?"},

openai[minor]: implement langchain-openai package (#15503) 
Todo

- [x] copy over integration tests
- [x] update docs with new instructions in #15513 
- [x] add linear ticket to bump core -> community, community->langchain,
and core->openai deps
- [ ] (optional): add `pip install langchain-openai` command to each
notebook using it
- [x] Update docstrings to not need `openai` install
- [x] Add serialization
- [x] deprecate old models

Contributor steps:

- [x] Add secret names to manual integrations workflow in
.github/workflows/_integration_test.yml
- [x] Add secrets to release workflow (for pre-release testing) in
.github/workflows/_release.yml

Maintainer steps (Contributors should not do these):

- [x] set up pypi and test pypi projects
- [x] add credential secrets to Github Actions
- [ ] add package to conda-forge


Functional changes to existing classes:

- now relies on openai client v1 (1.6.1) via concrete dep in
langchain-openai package

Codebase organization

- some function calling stuff moved to
`langchain_core.utils.function_calling` in order to be used in both
community and langchain-openai

Update _retrieve_ref inside json_schema.py to include an isdigit() check (#14745) 
- **Description:** Update _retrieve_ref inside json_schema.py to include
an isdigit() check
- **Issue:** This library is used inside dereference_refs inside
langchain_community.agent_toolkits.openapi.spec. When I read in a yaml
file which has references for "400", "401" etc; the line "out =
out[component]" causes a KeyError. The isdigit() check ensures that if
it is an integer like "400" or "401"; it converts it into integer before
using it as a key to prevent the error.
  - **Dependencies:** No dependencies
  - **Tag maintainer:** @baskaryan
