Block Editor Handbook: Parsing issue when a link is wrapped in code

[ndiego]

In the Block Editor Handbook, when a link is wrapped in backticks (`), it is not properly transformed into <code> markup in the Handbook. This PR is a good example.

It looks as though the markdown parser does not recognize the closing backtick at the end of the link. A temporary solution is to just wrap the link in actual <code> markup.
