Refactor/pydantic adjusts

[jlnav]

Pydantic v2 and v1.10.17 have a pydantic.v1 compatibility namespace/module that we can import everything we need from. This means that we only need a single interface (unfortunately, the old one) to be compatible with both versions.

This is much cleaner, but I wouldn't be surprised if there's a slight performance drawback if the validation in the v1 module only occurs in python instead of rust.

TODO: fix docs

[jlnav]

The docs issue may be related to autodoc_pydantic not supporting the BaseModel in pydantic.v1 ? I opened an issue here to investigate: mansenfranzen/autodoc_pydantic#302

[jlnav]

This may be blocked until autodoc_pydantic has an update. Thankfully these improvements aren't critical; closing for now.
