Add CI build for Python 3.12 (#829)

This PR enables Python 3.12 in Windows environment and does not restrict
Python version in the default environments on Windows and Linux. Note
that although `mlos-3.12.yml` exists, its usage is still commented out
in `linux.yml`, because Python 3.12 is still not available on GitHub CI.
Issue #832 opened to track it

P.S. Also, we now use a lighter `matplotlib-base` instead of
`matplotlib` proper

~To be merged after #802~
