chore: bump langchain-core from 1.0.7 to 1.2.6 (#190)

This pull request updates the version specification for the
`torchvision` dependency in both the `extractor-api-lib` and
`document-extractor` projects. The change allows for greater flexibility
in the accepted `torchvision` versions, making it easier to receive
compatible bug fixes and minor updates.

Dependency versioning improvements:

* Changed the `torchvision` dependency version specifier from an exact
version (`0.24.1+cpu`) to a compatible version range (`^0.24.1+cpu`) in
`libs/extractor-api-lib/pyproject.toml`.
* Made the same version specifier change for `torchvision` in
`services/document-extractor/pyproject.toml`.
