Pull command descriptions from Bukkit and Sponge versions when listing commands

This allows the description of the commands to display when listing the commands in bedrock by tab-completing. This is currently only available on Sponge and Bukkit versions as there is no support in BungeeCord and Velocity to get these values. This data is also not sent in any packet, so we cannot retrieve that from standalone either.
