✨ Support common pydantic types

[lachaib]

This PR is "functional" as in "it does what was expected"

• Support pydantic common types while keeping pydantic an optional dependency
• Works in lists and tuples
• Documentation with examples and test on examples

However, don't hesitate to request more tests, docs, or improvements on the code if needed to fit with the current standards

Fixes #181

@tiangolo in order to add a basic pydantic support, we'd need to drop python 3.6, and I'd say it's about time 😏
Would you agree with that? Do you want me to open another pull request to do so? I'd be glad to help.

Edit: seems it's already submitted here #556

Hi! Note that Python 3.6 support was recently dropped in 0.11.0.

Looks great, I'd love to see this get merged!

Could we somehow also support custom types defined by users like pydantic?

Me too 😁

TBH I think this PR covers most of cases we need for now and I prefer to keep it minimalistic to get a chance for it to be merged soon.
On a personal project I managed to go a bit further and I'd really be glad to see Typer include all the features I made (some from inspiration of existing PRs) but small steps are always better.

@tiangolo Is this PR being considered?

[svlandeg]

Hi @lachaib, thanks for this nice work! Really appreciate the detailed tests and documentation as well.

I'm going to spend some time going through this PR in detail - I might leave some more review comments in the process, and might also push a few changes directly to your branch 🙏

[svlandeg]

It looks like this PR is now failing, as we recently added Python 3.12 to the CI. I'll put this in draft while we work on it 🚧

[lachaib]

@svlandeg thanks for your additions, I'm wondering now what's next for this PR and how may we move forward to merging?
