acts: ensure Python_EXECUTABLE uses ^python when +python (#38540)

Browse Source 
By default, `find_package(Python)` searches from highest version to lowest version, identifying the highest version that satisfies the requirements. This means that `/usr/bin/python3.11` will be found before `$(spack location -i python)/bin/python3.10`, even when other packages have been built with the `python` in spack.

This ensures that the `python` dependency is explicitly the `python` version that is used.
