Add pre-commit hooks to container

As specified here

Run git hook installation setup either just inside Devcontainer or in Dockerfile as well.

As per instructions you can't actually force Git repository to use git hooks without user's opt-in. Which is a good thing, I guess. This means, that instructions need to be updated on that topic. Inside dev container I should think installation of Git hooks can be mandatory, so they'll work from inside Codespaces.

Agree. Dockerfile install was removed because otherwise papermill parameterisation tags were cleaned from the notebooks. Now this should not be an issue

The template should also be used dockerized by default, whether or not with code spaces
