Added support for pydantic-settings in Configuration.from_pydantic()

[tsaryapkin]

• Configuration provider can be initialised via from_pydantic method from both pydantic.BaseSettings (pydantic v1) and pydantic_settings.BaseSettings (based on pydantic v2).
• I also specified flask and Werkzeug (used by flask) versions because the latest version of flask seems to be incompatible with the library and lots of tests failed.

Hey @tsaryapkin , @rmk135

@tsaryapkin Thanks a lot for this update, I'm currently blocked from using this lib with a new project because of this issue and this would help a lot.

@rmk135 Is it possible to review this PR soon ?

Thanks !
