Add lint to prevent (most) URLs #104
Description
Summary
Many authors attempt to bypass markdown-rel-links by putting their URL in backticks:
Check out `https://google.com`.We should add a lint to make sure that all HTTP(S) URLs that are not hyperlinked (so in code fences, backticks, plain text, etc.) use example domains. Specifically, the following (and any subdomains thereof) would be allowed:
exampleexample.comexample.netexample.orginvalidtest
