（Java Parity）/seed command on bedrock edition

In the Java version, players can enter the /seed command to get the seed code of the current map. This command is not in the bedrock version. I know that the bedrock version can view the seed code in the editing and archiving interface, but this is not particularly convenient, so I hope to synchronize the function of the /seed command in the Java version. You can adjust whether the /seed command can be used by other players through other commands.
