fix: use of the right variable name (scaleform) (#378)

* fix: use of the right variable name

* Little nitpick on the variable name

Tested changes to make sure it works. I find the name scaleformHandle better than just scaleform, Lua is a dynamically typed language, and it's better to be descriptive for the non-familiar end-user. Great job spotting this by the way!
