fix: installing across volumes doesnt work

[Umbrason]

Purpose of this PR:

change the RetroRewind installation from using Directory.Move to File.Move to address the issue mentioned below

How to Test:

make sure WheelWizard and the Dolphin User folder are on different drives, then try installing RetroRewind.

What Has Been Changed:

I removed the Directory.Move call and instead copy over each file individually.
I also moved the cleanup of previous installations into the RemoveAsync() function.

I would suggest the following one-line change to fix the permission issue of 28.szs having ------x---:

WheelWizard/WheelWizard/Features/CustomDistributions/RetroRewind.cs

Lines 353 to 367 in b95f437

	// If it’s a directory, create it
	if (entry.FullName.EndsWith(Path.AltDirectorySeparatorChar))
	{
	_fileSystem.Directory.CreateDirectory(destinationPath);
	}
	else
	{
	// Ensure folder exists
	var dir = _fileSystem.Path.GetDirectoryName(destinationPath);
	if (!string.IsNullOrEmpty(dir))
	_fileSystem.Directory.CreateDirectory(dir);
	// Extract the file
	entry.ExtractToFile(destinationPath, overwrite: true);
	}

+    entry.ExternalAttributes |= Convert.ToInt32("644", 8) << 16;
     // Extract the file 
     entry.ExtractToFile(destinationPath, overwrite: true); 
 } 

I've tested this patch and it seems to work just fine now.
