Improved linkchecking

[VeckoTheGecko]

Describe your changes

Added Lychee linkchecking action workflow to the repo to go through repo files looking for broken links (404s etc). The workflow:

• Runs Lychee, checking for broken links. Generates a report with findings. Workflow always passes regardless of broken links
• If broken links found:
  • Automatically updates [AUTOMATED] URL Status Reporting #322 with the body of the report, and re-opens the issue if it was closed
• If no broken links found:
  • Automatically updates [AUTOMATED] URL Status Reporting #322 with a corresponding statement and closes the issue

Issue #322 in this case acts as the main mechanism for surfacing these broken links, in a way that is minimally intrusive (doesn't mess with GHA failures) and interested parties can subscribe to the issue.
