Move downloads into overflow menu on Branches view
Proposal
Move the download options into the overflow menu on the Branches pages and don't show the list of artifacts here.
In the past when we were looking to simplify the Branches list view #390925 (closed) we did not know what to do with the long list of artifacts that could appear
From !119637 (comment 1378516255)
This was a very sensible decision to keep the download button as is for now because of the artefact list can be very long.
Recently we have learnt that this list does not need to be in the downloads list #432363 (comment 1674045305) and was removed from the download dropdown of the directory view !138658 (merged).
