Switch to a newer SourcePawn grammar

[X6B0ISI09wD4]

Description

As discussed in #3156, a more up-to-date grammar would be ideal for SourcePawn. The syntax has changed significantly since the last changes to the currently used grammar.

Checklist:

• I am changing the source of a syntax highlighting grammar
  • Old:
    • New Syntax (>=1.7): Lightshow
    • Old Syntax (<1.6): LightShow
  • New:
    • New Syntax (>=1.7): Lightshow
    • Old Syntax (<1.6): Lightshow

Does the current contributing documentation mention having to run script/list-grammars and ensuring the TextMate scope selector is still correct? Not sure if I missed either of those.

Nope, because it is called by add-grammar which is documented as the method to use to add or replace a grammar.

/cc our friendly local Pawn expert, @50Wliu. Let us know if this grammar's carrying any red flags.

EDIT: I hate mobile keyboards.
