Alias Prometheus and drop the stale Azure icon note

Upstream ships this icon as promethus.svg, so the generated class inherits
the misspelling. Adding the alias now keeps the correct spelling available
without a breaking rename later.

The note in autogen.sh saying the Azure set is out of date no longer
applies now that the icons have been refreshed.
