Enhancement: Implement real Pydantic v2 support

[SupImDos]

Summary

• As raised by @lucidfrontier45 in support Pydantic v2 #48, we need Pydantic v2 support in pydantic-argparse.
• We now have pseudo-Pydantic v2 support, as the pydantic dependency is at least unpinned.
  • See: Enhancement: Pydantic v2 Package Shim Compatibility #55
  • See: v0.9.0
• However this is just a shim to the Pydantic v1 API.
• We should implement real Pydantic v2 support.
• I think maintaining both Pydantic v1 and v2 compatibility is probably unreasonable (TBD).
• More information to follow...

Notes

• Looks like our forks may have done some of the heavy-lifting

Dear @SupImDos,

Dear @SupImDos, is there any possible update soon?

Unfortunately I've been very busy lately, so its hard to put a timeline on things at the moment. I would say its definitely still on my radar, but I would be happy to accept PRs to get things moving. Sorry!

Thank you for your answer. No pressure. If I find some time, I'll try to put together some solutions from the other forks.

I just found out that pydanticv2 might support the functionality already: pydantic-settings

@noootch Oh wow, that's great! In that case, maybe this package should pivot to just supporting Pydantic v1 and eventually be deprecated / archived 🎉.

"might", I haven't compared the functionalities
