If you really want to be sure to always find python3 when running Meson (and not some other implementation like [Muon](https://muon.build)) it is a bit better to use `find_program('python3')`, as described in https://mesonbuild.com/Reference-manual_functions.html#find_program : "if the "python3" program is requested and it is not found in the system, Meson will return its current interpreter

Thanks for the not-so-quick merge! ;)
