Make april fool maps have the same name as normal maps (#3555)

## Description:

Make the april fool maps have the same name as the normal maps, in order
to make the prank better.

NOTE: In order for this to work, it re-adds the normal maps into
rotation. These normal maps have been given a lower rotation however.

In custom matches the maps will appear with the april fools names.

This change will be reverted after April Fools.

Check this for proof of it working:
