Explicitly search for Python to fix compilation with ECM 6.26

pybind11 has a bug [1] where the pybind11::embed cmake target does not get correctly linked to Python after a previous find_package(Python3) call without the Development component has been issued.

This affects audiotube after an ECM 6.26 change [2] added such a call, breaking compilation.

As a workaround, add an explicit find_package call for Python that includes the Development component and overrides the ECM one.
