build: staging script should ignore pre-commit hook (#15612)

Currently if the caretaker stages a new release, but does not have the
`git-clang-format` pre-commit hook configured properly (there is some
additional configuration involved), the staging script will fail.

In order to avoid these failures, we just ignore the pre-commit hook when
a commit is created automatically by the release scripts. The release script
only makes changes which conform with the clang-format's/ the project style
guidelines.
