Fix lib.bat file

[MrVitaly]

Changes in the lib.bat file:

• Creating the lib Directory: Ensures that the target directory exists before attempting to copy the files, preventing potential errors if the directory is missing.

• Using %LOCALAPPDATA% Path: This change enhances flexibility and correctness by copying the DLLs from the local user's application data directory, which may reflect the latest or user-specific versions of the PowerToys DLLs, rather than the global installation directory. This can be especially useful in environments where multiple users or versions exist.
