CI: Add Python 3.10 and 3.11, update actions (fixed)

[herati]

• The pypy v7.3.13, used by GitHub Actions, was failing. So I force to use pypy v7.3.12 that was passing.
• The original PR was done by @EwoutH at https://github.com/bndr/pipreqs/pull/334 and modified by @willianrocha at https://github.com/bndr/pipreqs/pull/398.
