Update Python Version Matrix in CI Jobs

• Python version 3.7 end-of-life (EOL) is due on 27 June 2023

• Using version 3.8 as a new baseline for this projects also allows us to make use of this feature list:

  https://docs.python.org/3/whatsnew/3.8.html

Notice that the version numbers are all now enclosed in single quotes. This is important in special situations, without that version 3.10 will be interpreted as 3.1 by GitHub Actions (and rightly, so!). Therefore, it's considered best practice to treat version numbers as strings, since version numbers can come in all forms or shapes.

Remark: pytest doesn't officially support the beta version of 3.12 (or the dev version of 3.13) yet.

This is a fantastic idea! There are some features I would like to take advantage off that aren't available in 3.7.
