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 !

@rmk135 Could someone review this PR that’s been sitting untouched for over a year?

[rmk135]

@naem1023 thanks for highlighting this. I started looking at the pydantic 2 support yesterday and came to a pretty similar idea on the implementation. This PR has already been implemented nicely (thanks to @tsaryapkin ).

However, we won't be able to merge it since there are a few merge conflicts. There have been a few changes made in the code since this PR was created. I'll see if I can resolve those conflicts myself or maybe will take the code to build a new branch and thank @tsariapkin for his contribution in the changelog and the contributors file.

@tsariapkin , if you have a moment to deal with the conflicts, that'd be much appreciated too. Otherwise, thanks for that contribution. Nicely done!
