This replaces the python in python.app if it is installed.

For reference, I did this for https://github.com/conda-forge/cctbx-base-feedstock/pull/16 and the relevant lines in build.sh are

# update python.app python on osx-arm64 to avoid Bad CPU type error
if [[ "$CC" == *"arm64"* ]]; then
  rm $PREFIX/python.app/Contents/MacOS/python
  cp $PREFIX/bin/python $PREFIX/python.app/Contents/MacOS/python
