tox.ini and CI: Move pytype to Py3.8 and remove 3.7 and 3.9 builds

- pytype has several problems to import libraries when used on
  Python 3.10, therefore move it Python 3.8.
- tox.ini, GitHub CI: Remove builds for 3.7 and 3.9 builds
  because they showed intermittent pytest failures and
  we shoud not used them as new Python versions anyways.
