Update Europe map and remove its Classic version off rotation (#3647)

## Description:

This was a proposal in the map channel of the dev discord server:

**Updates the Europe map to include Iceland, and removes Classic Europe
off rotation.** Classic Europe will remain in custom private map list

The only thing the new europe map didnt have from the classic version
was iceland, so i figured we should update the europe map to contain it,
since Iceland is a popular spawn in the classic version. Iceland is in
the same position as the classic map

The classic europe is frankly a lesser version of the new map as it
doesnt contain rivers , is smaller and the terrain has less quality, and
with the updated version, classic would just take up very needed space
in the lobby queue. We currently have a very large number of maps, which
results in players having to wait for a long time for an specific map in
public lobbies. This should help the issue a little at the very least.
