kdev-python: Use CMake FindPython3

[Casian Andrei]

Dear Sven*, *Björn, Francis,

I have read all your answers, thank you for all the useful information!

Succeeded in restoring the account on identity.kde.org and managed to 
create a proper merge request [1].

Things should be going smooth now.

Have a wonderful day!
