Is your feature request related to a problem? Please describe.

Be able to add a link to a Download on a text by searching for the Download in the link search.

So: Add Gutenberg Paragraph block, type text, select text, click button "link" and search for the Download.

Going to remove this from the Milestone, going to do this when Gutenberg evolves a little so we can change the subtype and icon.
