Support for PEP-735 (dependency groups in pyproject.toml)

[tfpf]

PEP-735 defined dependency groups for Python projects. Is there a way to specify those as environment dependencies?

Here's a hypothetical project.

# pyproject.toml

[project.optional-dependencies]
test = ["gcovr", "pytest-xdist"]  # OK: can reference them directly.

[dependency-groups]
docs = ["sphinx"]  # Need to repeat it for Hatch.

# …

[tool.hatch.envs.testenv]
features = ["test"]  # Referenced directly.

[tool.hatch.envs.docsenv]
dependencies = ["sphinx"]  # Repeated here.
skip-install = true

Building the documentation for this hypothetical project does not require the project to be installed, which is why Sphinx is in dependency-groups instead of project.optional-dependencies. (This is, in fact, one of the reasons dependency groups were introduced.) But I couldn't find a way to specify a dependency group in the documentation of Hatch environments. Is there an easy way to accomplish this?
