Run pre-commit into the CI

Would allow to run the same versions of the development tools in different environments: dev env, CI. It would avoid the issue of having the dev tools updated when updating the images and not of same version as the ones from pre-commit. They would all be updated for all environments when updating .pre-commit-config.yaml.

• Set up cache for pre-commit to speed-up jobs
• Run jobs with pre-commit

Image generation

• Uninstall no longer necessary dev tools from 3.8 image, once the migration has been completed
