Use pip corresponding to python executable (pytorch#141165)

Sometimes `python3` and `pip` are aliased to different runtimes, so it's better to always use `pip3`, but as linter should install packages into the same python environment, it's even better to just call sys.executable with `-mpip install XYZ` arguments

Fixes regression introduced by pytorch#124033
