Allow any number of Rooms when creating a space

### Your use case

When creating a space the user cannot choose the number of rooms that are created, you have to create at least 3 rooms, this might not always be necessary

Community testing feedback:
"There are suggestions of predefined rooms shown. In this view only the room names can be removed, but not the rooms themselves (without having them created it seems like that at least, it seem s like I am creating at least 3 rooms with potentially empty room names). Suggestion: add a cross or something like that to remove the rooms from the list"
