CI: Put pre-commit cache under CI_PROJECT_DIR (#11929)

* CI: Put pre-commit cache under CI_PROJECT_DIR

Apparently gitlab-runner can't cache stuff outside of the project
directory.

Put the cache under CI_PROJECT_DIR to make it work (which also means we
need to ignore it from ansible-lint).

Also update the pre-commit image while we're at it.

* update ansible-lint pre-commit
