Lock dependency groups in the `uv pip` interface, i.e., `uv pip compile --group`

[KasperZutterman]

Hi all,

Similar to #8590 it would be great if the PEP 735 dependency-groups could be locked with uv pip compile.

I would imagine something like: uv pip compile pyproject.toml -o requirements-dev.txt --group=test.

Linking this for possible interface alignment:

• Eventually implement support for the PEP 735 "dependency groups" jazzband/pip-tools#2062

👍 We'll do this, likely as soon as the interface is defined for pip itself.

Until it is implemented you can always help yourself with some scripting hacks (maybe use https://github.com/kislyuk/yq for a more reasonable script):

 sed -n "/\[dependency-groups\]/,/\]/p" pyproject.toml | grep -E '^\s*"[^"]+"' | sed 's/,$//' | sed 's/"//g' | uv pip compile - >> requirements.txt

But this won't respect the lock file.
