Lighting removal command is unknown by the server, after being suggested by it

[NotFury]

A command was offered to remove lighting when I was world editing on World's realm; "//replace #brightness:1:15 0". Upon trying this command, I was given "Unknown mask: #brightness:1:15 See: //masks

To Reproduce Steps to reproduce the behavior:

1. //paste an object multiple times until the suggestion comes up.
2. Attempt using "//replace #brightness:1:15 0"
3. Receive an unknown mask response by the server.

That's not the right way to use that particular pattern. You need to use //replace #brightness[min][max] air and it will replace all blocks with light level between min and max with air. You need to use brackets with all the arguments for masks and patterns.
