Do not blindly assume python3 is also the interpreter that runs rst2html

On my system python3 is the macOS system python3 while rst2html has

   #!/opt/homebrew/opt/python@3.9/bin/python3.9

as its first line. Running that with a different python results in missing
python modules. So directly execute the rst2html script instead.
