Upgrade to debian Buster slim (later to debian bullseye, crosstool-ng must be updated first, version 1.23 is not compatible with debian bullseye)
Disable python script (build-and-install-python.sh), the version of python in the repositories is recent enough for crosstool-ng 1.24 and above.
Changed from python to python3 for compatibility
Adding the manual launch of a github workflow
