Refactor zstd decompression handling in expand-windows-installer.mjs

- Updated the findZstdDecompressCommand function to improve compatibility with Windows by adding shell options for command execution.
- Simplified candidate path resolution for zstd executables by utilizing a dedicated electrobun directory, enhancing clarity and maintainability.
- Improved error handling during decompression and extraction processes to ensure better reliability on Windows platforms.
