Exclude published RFCs from automated checks

The development and maintenance of the contents of this repository is facilitated by the use of tools, both locally by
the contributor, and automatically on relevant changes by the continuous integration system.

New issues may be detected by updating to a new version of a tool, or improving its configuration. In the case where
this is in a published RFC, it is difficult to know how to proceed. Although a new revision may be created, standard
practice is to not modify published RFCs. Creation of a new revision would not be appropriate for a minor typo or
formatting fix.

For this reason, the best approach will be to configure the tools to ignore the published RFCs.

The exception is the link check, since we may be able to fix broken links to pages controlled by Arduino (e.g., by
setting up external redirects).
