Allow @p target selector in /broadcast and /warp commands for commandblock usage in 1.20

[Waterman1001]

In our server, we use command blocks in combination with the /broadcast and /warp commands.
This way, if players stand on the pressure plate on top of a command block at the end of a parkour, it announces to the rest of the server that the parkour was completed by the player and it teleports them to a specific essentials warp with /warp @p .

For this, we used to use the @p target selector, because it is the closest player who should be broadcasted (/broadcast @p has finished the server parkour!) and teleported. Unfortunately, since quite some versions now, the target selector for command blocks is not supported in plugin-commands anymore, but only vanilla, unless it is implemented specifically using the Bukkit#selectEntities Bukkit API created for it:
(https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Bukkit.html#selectEntities(org.bukkit.command.CommandSender,java.lang.String))

Before, we used the plugin CommandHook, in order to still be able to use this. However, currently CommandHook is not yet updated to Minecraft version 1.20.2, and therefore I thought: perhaps this is a good moment to become less dependent on the CommandHook plugin, and simply request target selector (specifically @p) support for this essentials command by EssentialsX in its core! 😄

It would help me as a server owner a lot, simply because it makes us less dependent and allows us to use commandblocks with the broadcast and warp commands.
Thank you a lot for your understanding in advance!

Best regards, and thanks for the considerations! 😊
