Enhance uninstallation script and improve comments

[relvinarsenio]

Summary of Changes:

• Added delayed expansion to enable variable modification within blocks
• Corrected variable usage and calculations
• Improved error handling and folder removal process

Details of Changes:

1. Added Delayed Expansion:

   • Enabled delayed expansion using setlocal enabledelayedexpansion
   • This allows variables to be updated and accessed within loops and blocks

2. Corrected Variable Usage and Calculations:

   • Corrected variable usage for counting removal operations
   • Changed set /a b=!a! + 1 to set /a b=!b! + 1 for accurate counting

3. Improved Error Handling and Folder Removal:

   • Added error handling for Spotify uninstallation process
   • Utilized a loop to remove Spotify data folders: "%appdata%\Spotify" and "%localappdata%\Spotify"
   • Changed the variable a to b for counting removal operations consistently
   • Improved deletion process of "SpotifyUninstall.exe" if it exists

4. Output Messages:

   • Improved output messages to provide better feedback:
     • If no removals were performed: "Spotify not found"
     • If removals were performed: "Spotify removed"

These changes ensure the script's functionality, accuracy, and clarity.
I've tested this script on my computer and successfully executed it without errors.

Please review and merge these changes if they meet the desired improvements.
