1951411 - Remove islamic-rgsa from list of supported calendars

The islamic-rgsa calendar delegates to the islamic calendar in ICU4C and is not implemented in ICU4X.

Since this calendar depends upon astronomical sightings by a person, it is impossible to predict in the future, and would require look up tables to support properly in the past. There's no reason to ship this to the web.

I've experimented with this a bit this morning, but there's not really a clean way of filtering out islamic-rgsa from our code, there's multiple integration points with ICU4C calendar code through DateTimeFormat and DisplayNames. Unfortunately, I think this will have to wait until we move to ICU4X.
