Remove Python 2

[avdv]

Is your feature request related to a problem? Please describe. I noticed we are building python2 from nixpkgs in our CI pipeline:

  these 2 derivations will be built:
    /nix/store/9mkxvfagi24m76w1p8gb6wrq282p3ssx-python-2.7.18.7.drv
    /nix/store/rifad05gvk9c7acxsqhhc1l6ipgxiyjm-test-nixpkgs-python-toolchain.drv

Python 2 has been sunset a few years ago and should no longer be used.

Describe the solution you'd like Remove any PY2 targets from tests and python2 nixpkgs_package calls.

Describe alternatives you've considered Leave it as is but mark the targets as manual.
