Read test cases from toml files

[cclauss]

Just a little experiment... I left the current tests in place while adding tests that are read in from a cases.toml file so we could see both approaches side-by-side. Feel free to close with unmerged commits.

This is great! Thanks @cclauss :)

Do we want to keep helping? My idea would be for each toml to be a "project", and run bump-pydantic on each "project". This way we could separate the test cases by "projects".

[cclauss]

Sure... A few things to look at... -- EDIT: Merged in #88

About the input and id, I don't mind changing it and enabling that rule.

About the B008, it needs to be ignored. That's how Typer works.

About the PT, I'm fine about adding it, and fixing with --fix.

Ready for review.... I left the folder-in-folder thing in Python but the others are in toml.

[Kludex]

Hmmm... I want to have a way to have folders in the TOML, and have each toml to be a separate test case, so I can specify with pytest the one I want.

[cclauss]

pytest --capture=sys --showlocals -vvv tests/integration/test_cli.py runs in about 2 sec. so running individual toml files seems like overkill that might allow developers to overlook breakage in other tests.

I will reexamine folders-in-folders over the weekend.
