* Send message to Java if command is Bedrock-only
If a Java player attempts to use a Bedrock-only command, such as `geyser statistics`, they will get an error message stating that this command is only for Bedrock players.
This commit also cleans up Velocity Adventure dependency usage. Issues were caused because of the way relocation works and because Velocity also uses Adventure.
* Only look for a session if we have to
* Update languages submodule
* Introduce CommandSender.getLocale()
This allows Geyser-specific commands (e.g. `/geyser help`) to be displayed in the (Java or Bedrock) player's default language, which stops those commands from simply being displayed in the default locale.
* Tweak Javadoc
* Set CommandManager's GeyserConnector to final
* Clean up
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.
