(doc) Add documentation of new rule CPMR0075

We are planning to implement a new requirement rule for blacklisting
URLs that come from GitHub comments. As this is a new rule without any
associated documentation, we need to create the documentation that is
related to this rule.

+## Issue
+
+Within one or more of the automation scripts, one or more URLs were found to point to a GitHub comment file or asset.
+
+## Recommended Solution
+
+Use the official download location of files from the software authors that are not part of a GitHub comment.
+This can be URLs on their official web page, from their GitHub releases, or from a third party that is officially endorsed by the software developers.
+
+## Reasoning
+
+Since any user can upload files to a GitHub comment, even without publishing the comment, this can be used as an attack vector by malicious actors.
+To prevent such misuse from happening and affecting our users, it has been decided to disallow these types of URLs.
