Hatch crashes if plugin namespace has dots in entry points

In my pyproject.toml I have the following entry point:

[project.entry-points.iqe.click_commands]
requirements-report = "iqe_requirements.cli:requirements"

When I do hatch build, hatch crashes with the traceback:

Traceback (most recent call last):

Looks like hatch doesn’t expect a string with dots in plugin-namespace .

[RonnyPfannschmidt]

is this a “under-spec” issue, in PEP-621

as far as i understood it may be necessary to make the key [project.entry-points."iqe.click_commands"]

I’ll fix, thanks!
