Update macOS Intel installer workflow to use macOS 13 and simplify architecture handling

- Changed the runner from macos-latest to macos-13 for improved compatibility.
- Removed explicit architecture specification for pip installations and PyInstaller, allowing native execution.
- Updated comments for clarity on the build process.
