  Use python3 not python
  
  As per https://peps.python.org/pep-0394/, the python binary can be one
  of the following options:
  - Python 2
  - Python 3
  - Not exist
  
  All of the scripts in libxml2 use 'python', which may not exist.
  
  As Python 2 reached EOL on the 1st January 2020, it's safe to move the
  scripts to use python3 explicitly.
