Try to fix Lychee github action error (#1034)

This fixes the Lychee GitHub action so it doesn't fail on each PR

- Do not run as a PR check
- Run against `main` using a cron schedule, for 12:01 AM on the 1st of
each month
- Ignore 429 errors
- Adjust the syntax for specifying args
- Give it permission to create GH issues
- Upgrade the action
