(🎁) canwecolor🚀 (#14051)

Last time i checked it wasn't the 1960's. So I think the CI could be
colorized.

Configured pytest, tox, mypy(#7771) and pip¹ (I already already
colorized black and isort when I initially added them)


1: Pip doesn't work yet pypa/pip#10909, so
this is just a placedholder for when it (hopefully) soon will.
