Creating the /unmutechat command

In this step, we'll write the command for the unmute chat script.

We'll do the same thing as the /mutechat command, but we'll change the values of the messages and variables.

The variable name must remain the same, but the value must be changed. Going from "on" to "off"

The message itself should be changed to "[Player Name] has muted the chat."

Simply remove the "Get Player Name" element from the unmute chat message to remove the name.
