support pydantic v2

[sanzoghenzo]

Hi! great to see this useful tool!

Cross posting from FastAPI discussions 😉

I just tried it, but unfortunately it doesn't work with pydantic v2.

It crashes because it can't find pydantic.fields.ModelField, that is removed in facor of a cls.model_fields, which is a dict[str, FieldInfo].
Obviously there will be other error, but I couldn't find the time to investigate it further.

The work is almost finished, but when I checked the tests from V1 to V2, I found a problem with the incorrect parsing of Optional[list[...]], Optional[set[...]] and other types for FORM , because of which I had to spend time and make a PR in FastAPI.

But need to wait for it - fastapi/fastapi#9925 & fastapi/fastapi#9928

I made a fork with support for version 2 -
