This PR upgrades langchain-community to pydantic 2.
* Most of this PR was auto-generated using code mods with gritql
(https://github.com/eyurtsev/migrate-pydantic/tree/main)
* Subsequently, some code was fixed manually due to accommodate
differences between pydantic 1 and 2
Breaking Changes:
- Use TEXTEMBED_API_KEY and TEXTEMBEB_API_URL for env variables for text
embed integrations:
cbea780492
Other changes:
- Added pydantic_settings as a required dependency for community. This
may be removed if we have enough time to convert the dependency into an
optional one.

This repr will be deleted prior to release -- it's temporarily here to
make it easy to separate code changes in langchain vs. code changes
stemming from breaking changes in pydantic
This PR adds methods to directly get the json schema for inputs,
outputs, and config.
Currently, it's delegating to the underlying pydantic implementation,
but this may be changed in the future to be independent of pydantic.
Upgrading the langchain package to be pydantic 2 compatible.
Had to remove some parts of unit tests in parsers that were relying on
spying on methods since that fails with pydantic 2. The unit tests don't
seem particularly good, so can be re-written at a future date.
Depends on: https://github.com/langchain-ai/langchain/pull/26057
Most of this PR was done using gritql for code mods, followed by some
fixes done manually to account for changes made by pydantic
