Academy Python based tutorials have been bumped to Python 3.10

Some Academy courses include Python based tutorials (with source files available on github). These have been now tested using the 3.10 version of the Python interpreter. The 3.10 version will be supported by PSF until 2026.

There are some minor bugs in some scripts and examples that will be fixed in the sequel but it is recommended that students of Python related courses already consider upgrading their setup to 3.10.
