Reenable and enhance copr integration tests (#5638)

* Enhance `copr` integration tests

- Switch to a new test Copr repository. @copr/integration_tests was
  removed which caused the tests to fail. I created a new one under my
  account that I'll ensure stays around.
- Add basic testing to ensure that repo files are created in the correct
  location and contain the correct baseurl and enabled status.
- Also run tests on Enterprise Linux.
- Test that packages from the Copr install. This has to be disabled on
  EOL Fedoras that Copr does not allow building new packages for.

Resolves: https://github.com/ansible-collections/community.general/issues/5595

* copr tests: Fix ansible_python_interpreter on c8s

* copr: Don't test on alt Pythons on cs8

* Revert "copr tests: Fix ansible_python_interpreter on c8s"

This reverts commit 58e15a7ebf.
