Is there any benefit in generating _version.py?

[coretl]

In #81 @garryod changed to get __version__ from importlib.metadata:

python3-pip-skeleton/src/python3_pip_skeleton/__init__.py

Lines 1 to 3 in 913fd74

	from importlib.metadata import version
	__version__ = version("python3-pip-skeleton")

This means that we require the module to be installed so we know the version. This means that _version.py is not used, ever. We can clean up here, and stop generating it:

python3-pip-skeleton/pyproject.toml

Lines 50 to 51 in 913fd74

	[tool.setuptools_scm]
	write_to = "src/python3_pip_skeleton/_version.py"

and ignoring it:

python3-pip-skeleton/.gitignore

Line 26 in 913fd74

**/_version.py

@garryod @GDYendell @gilesknap @AlexanderWells-diamond: any reason we should not do this?

The other option would be to change __init__.py to always import from _version.py:

try:
    from ._version import __version__
except ImportError:
   __version__ = "not-installed"

[coretl]

but maybe importlib is more standard

[GDYendell]

I think #81 removed the ability to check versions with a git archive and that is what checking in the _version.py is for, right?

[coretl]

But _version.py is not present in the archive, so I don't think it's that either...

I think it isn't giving us anything now then.
