`pip3` instead of `pip` on macOS with Python3

[nhoizey]

It looks like the binary of my installation of pip with Python3 on macOS 13.3.1 (Ventura) is named pip3 instead of pip.

I don't know if it's the same on other OSes.

pip3 is the Python 3 version of pip, that and other things I've seen are a sign this project hasn't been touched in forever, and is basically broken until the developers start maintaining it again.
