About gamemode command

After 1.13 or 1.14 came out, im not glad of the new style of /gamemode command.

In older versions, we were able to write and use that command faster and more practice.

It was "/gamemode {1,2,3,4}". But in new versions, this got changed and we have to waste our seconds writing /gamemode commands. I suggest you to bring this old method back and let us choose how we will write this command.
