[feature request]: Add a new rule validate decorators

I found this could be useful if we want to enforce the code to use always specific rule in decorators e.g always use `OnPush` change detection

Start by reviewing the two referenced Angular component pull requests and the repository's existing rule structure. Define the decorator patterns to validate, including the OnPush example, and consider the work complete when a new rule consistently enforces the specified decorator usage.
