contrib: print the version of pytype used to do the type checking
This will help with CI. I don't see a way to print the version of python that's
running it. When I tried `head -n 1 $(which pytype)`, the CI run printed:
#!/usr/bin/env bash
Locally, that gives the path to the python interpreter in the venv, so IDK
what's different.
