[FEATURE] Support for v1 recipies

[ShalokShalom]

Is your feature request related to a problem? Please describe.
I think the use case is pretty clear: The new format is supposed to supersede the previous one.

Describe the solution you'd like
Full support for the new format.

Describe alternatives you've considered
Using Grayskull, and then adjusting the output by hand.

@conda/grayskull,

Is there an opportunity for someone to pick this up? I'm interested in working on it because I think it could be a great way to promote v1 usage because a lot of incoming recipes to conda-forge/staged-recipes are still using v0. I'm assuming this happens because grayskull still defaults to and only supports v0.

It would be great if someone implements this.

The PR for the V1 recipe format has been merged lsat year, but does that mean it's not a complete implementation?

#539

There's a -u,--use-v1-format flag folks can use, but it's labeled as experimental.

Yep, as of #31330 on staged-recipes, --use-v1-format is the default when using pixi run pypi, and the README.md suggests the new flag as well. But indeed, muscle memory is a powerful thing.
