Update outdated line (#1065)

## Changes

Roblox has changed where the versions/Roblox folder installs, so I
updated the outdated line.

You can confirm this by going to this location:
C:\Program Files (x86)\Roblox\Versions

You will see that Roblox's version folder is now there instead of
C:\Users\Your_User\AppData\Local\Roblox
