No pre-commit config in the baked template repository

[dokempf]

When generating the bake that gets auto-synced to https://github.com/ssciwr/python-project-template, we do not have pre-commit installed and therefore do not generate a pre-commit config file. However, we do run pre-commit CI on that repository, resulting in a failure like this: https://results.pre-commit.ci/run/github/317173799/1782997551.CtMGcjyzTTSj_CJq7hdkgw

Easiest fix would to just pip install pre-commit into the environment when installing cookiecutter.
