Replace Minecraft Realms button with a Minigames button that has buttons for all the minigames that have a configurable server IP

I agree with what @DBTDerpbox said, I won't replace realms button, as some players use realms, but there'll probably be a Minigames button in future versions.

Removing realms functionality wouldn't be the best idea so either moving realms to the join menu with a "realms" button under add server or having Minigames under realms in the main menu might be a better approach
