Cleanup tox.ini
We remove install_command because the value set here is basically the
default but with one small difference. It doesn't run using `python -m
pip` which means we could potentially find a global pip install which
installs to the wrong python by default. Using python -m pip as the tox
default does should ensure it consistently finds the venv pip.
Additionally we stop allowlisting all external commands to make problems
like this more apparent.
