Find alternative action for markdown link check

[vishnuravi]

Problem

We are currently using gaurav-nelson/github-action-markdown-link-check@v1 for our markdown link checker. However, per its README the author is no longer maintaining it. The current action has a number of limitations and false positives (as the author notes) which will not be addressed.

Solution

We can look into other suitable alternatives, or write our own. The author of the action we are currently using also notes that he is working on a new action, which we can consider when it is finished.
