Replace template CI from AppVeyor -> GitHub Actions

[bluetech]

This is the more common/easier choice these days, and also doesn't run only on windows(?).

and also doesn't run only on windows(?).

AFAIK it supports all platforms, in fact GH Actions runs on Azure. But definitely using GA is the way to go here. 👍

tox -e py runs using the current interpreter, so this can be simplified:

The raw is escaping for the Jinja template language which cookiecutter uses, otherwise the ${{ .. }} is interpreted by Jinja.
