MNT: Get rid of minversion definitions in init.py

See original GitHub issue

Description

Do we really need all this stuff in __init__.py? It duplicates the info in setup.cfg anyway. For the usage in docs/conf.py, there is no reason we cannot get that info from setup.cfg instead?

https://github.com/astropy/astropy/blob/a995665c06b8d145ba811e3cbc59b0dfb8d20bd6/astropy/__init__.py#L15-L30

Additional context

If the package being checked has no __version__, importing astropy will fail. For example: liberfa/pyerfa#60

https://importlib-metadata.readthedocs.io/en/latest/ (not importlib-resources 😉). It would be a requirement for Python 3.7 only. In the long term it’s the package to use as it was designed as a more efficient replacement to pkg_resources. (We could also use it for entry points, it should be must faster)

Seems very nice. Could have a switch in __init__.py between pkg_resources and importlib.metadata… (see comments in PR)
