Added workflow to check links in docs

no issue

Added a little test to extract the links in the details property of a rule. Not part of the official test suite since it hits ghost.org a bunch.

Configured to run weekly
Can also be manually triggered

This is a very basic starting point that can be expanded as needed 😊

Things it does:

Ensure a tag has a link, and that link points to a WHATWG-compliant URL
Ensure a tag contains target="_blank"
Ensure links point to a ghost.org site
Ensure links are not redirected (non-fatal)
Ensure IDs referenced in a link are valid
self-rate-limits (5 URLs / 150ms right now)

Things it doesn't do:

Tell you where a link was redirected
Dedupe rule list - we could get away with only handling new rules of a test suite, but I didn't want to change existing files in this PR.

Things it could do in the future:

Only extract the list of URLs + IDs that are referenced
More validation checks
