latex: highlight $ $$ \[ and \( math modes properly.
These math modes were being split apart by control sequence regions.
To avoid this, they must be their own regions.
Fixes https://github.com/mawww/kakoune/issues/5249 .
Also, I got rid of an errant / in the control sequence ending regex that couldn't be right.
