Update poetry lock to allow SQLAlchemy v2
It seems that jupyter-cache is another blocking dependency:

jupyter-cache
https://github.com/hwchase17/langchain/blob/master/poetry.lock#L2526
https://github.com/executablebooks/jupyter-cache/issues/92
https://github.com/executablebooks/jupyter-cache/pull/93

This dependency was introduced in [pull request #534](https://github.com/hwchase17/langchain/pull/534/) but `jupyter_cache` doesn't seem to be called anywhere in the code base when you do `grep -r "jupyter_cache" .` in the root directory of the project. `jupyter_cache` is a dependency for myst-nb which is used in creating the docs. [I do have a PR open with `jupyter-cache` to allow SQLAlchemy 2.](https://github.com/executablebooks/jupyter-cache/pull/93) Thanks for the clarification and your efforts. Added some reactions and a "+1".
It seems that #1578 adds support for SQLAlchemy v2 but the [poetry lock file](https://github.com/hwchase17/langchain/blob/8685d53adcdd0310e76349ecb4e2b87f980c4673/poetry.lock#L6211) is still at 1.4.46.
