PEP 735 Dependency Group support?

[chrisjsewell]

Heya, both uv and tox have now added support for this:

• Add dependency-groups support (PEP-735) tox#3409
• Support for PEP 735 astral-sh/uv#8272

I haven't checked yet, but do you know if this should already now work for tox-uv, or would changes be required?

I note that it is not yet supported for uv pip, nor pip itself (pypa/pip#12963), if that makes any difference

I tested passing groups to uv_sync_flags with this configuration (with the new tox 4.21 native toml configuration support), as suggested in #113, but without success at the moment.

[tool.tox.env.doc]
runner = "uv-venv-lock-runner"
uv_sync_flags = ["--group=doc"]
commands = [
    ["sphinx-build", "--builder", "html", "doc", "build/sphinx/html"],
    ["sphinx-build", "--builder", "man", "doc", "build/sphinx/html"],
]

It fails with TypeError: '--group=doc' is not list.
