Switch to hadolint-py and add shellcheck-py

[martinhoyer]

See: https://pre-commit.ci/

In order for it to work, it requires adding pre-commit.ci in gh organization settings. (not doing that without consensus)

Can go hand-in-hand with #2923

One motivation is to keep the checks autoupdated, for example #3544 (comment)

GitHub action:

this action is in maintenance-only mode and will not be accepting new features.
generally you want to use pre-commit.ci which is faster and has more features.

pre-commit.ci will always be free for open source repositories.
Also adding shellcheck.py while keeping the shellcheck action - Closes #2271

pre-commit.ci doesn't play ball with pyright. For now, reverting to github workflow. Keeping hadolint-py and shellcheck-py

I have not had much experience with pre-commit-ci, but iirc it rebases open PRs, so I am ok with either this or renovate as a tool.

LGTM:)

[mcasquer]

Since renovate addition should handle the rebases part, LGTM

Nothing is ever easy.

Not sure if the tmt-lint works with the - GIT_DEPTH: "1" or not now.

ok, reverting to github workflow. Keeping hadolint and shellcheck changes.

Seems harmless & pre-commit only, merging without more checks.
