feat: add generic gh action

[leo-dur]

Add a generic composite action to run pre-commit from the CI.

It's a replacement for https://github.com/pre-commit/action because:

• it's a deprecated action
• it restores the cache for each hook-stage
• painful to use with hooks of type commit-msg

Note1: Might be better to put this action in its own repo.
Note2: The action is deprecated because they are pushing for their own CI (which cames with its own cons)

Ex of usage: https://github.com/Kpler/ct-webserver/pull/1894

It looks quite nice!
