rules_python is declared as a dev dependency but is an actual dependency

I tried to use the SBOM rule:

The fix we would like to make is to split rules_license into two modules in the same repo. One with just the declarations and one with the tools.
It will remain a dev dep for the license() and license_kind() rules, but a real dep for the tools.
