link validator CI failing

[pjfanning]

• https://github.com/apache/pekko-connectors/actions/workflows/link-validator.yml
• for this repo, link validation CI is only done once a week on a schedule - not for every PR
• the job has been failing for a while but don't link validate license report #899 made it worse
• raised Docs: Investigate why we end up with http links in our scaladocs #920 and Docs: Investigate why scaladoc links for pekko-http and pekko-grpc are broken #921 to follow up on remaining issues

(in pekko-grpc I had to remove the ./ from root-dir: https://github.com/apache/pekko-grpc/pull/400/files#diff-2a4ceebcb5b6c8bab1e5727bc9d87843f8f5c73f41c024b37acea23edb532ce7R4)

thanks @raboof - that helps progress.

There are some issues not associated with license report and I'll look at those now.

Still hitting issues with scaladoc links.

I suppose we can add them to ignore-prefixes and create an issue for the problem?

[raboof]

Great!
