Blender Shapekey Driver Slider for 3.0+ has been launched!

Wanted to see if I could fix up this code from 7 years ago! Ended up making it work with the help of chatGPT pointing out what was wrong with it.
Thought people would like this quick thing, so made it available here! Do tell if it gives off any bugs.
