Merge #15170: refactor/lint: Add ignored shellcheck suggestions to an array

cbd9091 refactor/lint: Add ignored suggestions to an array (Vidar Holen)

Pull request description:

  By adding excluded shellcheck suggestions to an array, you can avoid the current duplication
  between command and comments. This ensures that they never go out of sync, makes it easier to
  add new ones, and improves the readability of related diffs.
