Both Appveyor and Travis are outdated by configuration.
This PR adds Windows and Linux, both validating with version 3.6, 3.8 and 3.12 of Python.
The version 2.7 is no longer supported by setup-python. It's possible to introduce it, but requires a workaround. I prefer to wait someone asking or reporting a bug, otherwise, does not worth.
