Subject: [PATCH] refactor(schematics): resolve rule directories automatically
 (#12958)

* Instead of hard-coding the rule directories and potentially forgetting about adding directories if new rules have been created, we automatically resolve the directories through `glob`. Glob is already used in various schematic parts, and can be used here as well.
