bug#70167: [PATCH] Mark Flymake regions more accurately in lua-ts-mode

[john muhl]

This changes the diagnostic region end position from being guessed
based on thing-at-point to using the one provided by LuaCheck. As
noted in bug#67152 it was already being matched but not used. I
couldn’t find anything where t-a-p guessed wrong but it seems
preferable to just mark exactly the same region as LuaCheck would.
