Exclude subfolders from project in order to track main, and subfolder language domains.
For example:
domain.com (main)
domain.com/collection (still want to track)
domain.com/de/ (language subfolder we want to track)
domain.com/de/collection (also want to track)
But we dont want domain.com to read the language-subfolders into the main project since this would both waste crawls but also clutter tthe main domain with language specifics
