[bug#47663] [PATCH] website: Add Help dropdown menu

Hello Luis,

I find that this new dropdown provides an easier access to the Help
links which is nice!

What do we do with the old help/index.html page, that is now not
accessible? Maybe we need to remove this file:
artwork/website/apps/base/templates/help.scm?

Also I noticed that left clicking directly on the "Help" menu causes
some undesired wrapping on the Help items.

Thanks,

Mathieu
