[Feature] Hide nametag

[athyfr]

It would be great to have a way to hide nametags, even when not crouching.

The commands for this could be /hide and /unhide

Currently, a workaround is possible: Enable nickname nameplates, disable nickname prefix, and set the nickname to an empty string (''). However, this still leaves a little sliver.

Other mods exist for this, but most of them aren't actively maintained, and don't include LuckPerms integration.

Thanks!
