Cache Bukkit Command when wrapping CommandNodes

Browse Source 
Resolves https://github.com/PaperMC/Paper/issues/11378 by "restoring" the Spigot behavior where VanillaCommandNodes are only created once. This allows command frameworks that insert CommandNodes directly into the Brigadier dispatcher to change the permission String of the VanillaCommandNodes created for their commands, rather than it always being the default `"minecraft.commands.<name>"`.

Previously, BukkitBrigForwardingMap would create a new VanillaCommandWrapper each time a CommandNode was requested via the Bukkit CommandMap. This means that calls to `Command#setPermission` would not persist between retrievals from the map.
