Fix handling of 'Favorite Songs' playlist

[shafreeck]

Description

This PR fixes a crash that occurs when downloading the 'Favorite Songs' playlist. The issue arises because this automatically generated playlist lacks the curatorName attribute, which was previously accessed directly.

Changes

• Modified get_playlist_tags() to handle missing curatorName attribute
• Set default curator to 'Apple Music' for system playlists
• Improved error handling for playlist metadata

Code Changes

def get_playlist_tags(self, playlist_attributes: dict, playlist_track: int) -> dict:
    tags = {
        "playlist_artist": playlist_attributes.get("curatorName", "Apple Music"),
        "playlist_id": playlist_attributes["playParams"]["id"],
        "playlist_title": playlist_attributes["name"],
        "playlist_track": playlist_track,
    }
    return tags

Testing

• Tested with 'Favorite Songs' playlist
• Verified compatibility with regular playlists
• Ensured playlist metadata is correctly saved
