Enable dependencies from `dependency-groups`

[arunoruto]

Currently, the docs group should be under project.optional-dependencies, but that gets also shipped to the end user. Package managers like uv add the groups under dependency-groups.

It seems like the following PR enables specifying dependency-groups needed to be installed: pypa/pip#12963
I am not sure if it is already available, but I would keep an eye on it :)

Feature	project.optional-dependencies	dependency-groups
Scope	Published	Local
Purpose	Optional features for users	Dev/internal tools
Installation	pip install package[extra]	Not for end users
Core Functionality	Enhances, not required	Not part of package

That sounds good, thanks for you information, I wonder if this change is shipped in the latest pip?

I am unsure since I mostly use uv to manage my dependencies.

But for now, I found a temporary solution for this use case:

jobs:
  docs:
    runs-on: ubuntu-latest
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    permissions:
      pages: write
      id-token: write
    steps:
      - name: Setup | Checkout repository
        uses: actions/checkout@v4

      - name: Setup | Install uv
        uses: astral-sh/setup-uv@v4

      - name: Setup | Export requirements
        run: uv export --no-hashes --only-group docs > ./docs/requirements.txt

      - id: deployment
        uses: sphinx-notes/pages@v3
        with:
          checkout: false

P.S. uv follows PEP, so they don't implement their own needed sections in pyproject.toml, like it is done by poetry -> it can be used for projects that are not managed with uv.
