🦺 Validation check - Check that new markdown files match a recognized type

The Pain 🤕

People can merge new markdown files into rules that don't match any of the recognized content types. There have been several occasions where people have merged in a new rule and it hasn't gone live because it was placed in the wrong folder/had the wrong name.

💡Solution

We can add a validation check that uses the diff to check if any of the new content matches an existing category using the file path.

Tasks

• Update rules validator to check the directory of new files to see if they fit an existing category
• Update the validator to check the category of the new markdown file (If the path doesn't match) to generate an informative error message

Acceptance Criteria

• All existing rules pass the new validation check (I have a script that can check this, message @Calinator444 if needed)
