CMake: Improve python version mismatch error 

When CMake detects and incompatible Python version
it errors out with an error saying at-least python 3.9
is required, but doesn't mention the version it detected.

This makes troubleshooting the problem harder than it
needs to be.

This diff changes the error message to include the python
version CMake detected.
