Update the syntax of Autohotkey

[thqby]

Describe the enhancement

AutoHotkey v2 has been officially released for more than a year, and it is the main version at present. In this month, v1 has stopped maintenance. AutoHotkey in github still uses the old syntax for language highlighting, so it's time to update it.
