Ryan Roden-Corrent 4677502d7c Include gdscript warning name in LSP message. 
My initial attempt changed this in the gdscript code, which resulted in
a duplicate warning name in the builtin editor. We should just append
the warning name in the LSP instead.

This uses parens to match what is shown in the builtin editor.
