[Fix] Account for spaces in GOG game save paths on Windows (#3783)

* [Fix] Account for spaces in GOG game save path in Windows

Removes quotation marks from GOG game save paths for cloud sync.

The way we pass arguments to PowerShell already handles spaces in the path and the quotation marks added by getShellPath() causes paths to get truncated at the first space if they contain any.

* remove quotes from getShellPath() directly instead of working around it
