 If you hadn't published the Filament configuration file to `config/filament.php`, Filament will now reference the `FILESYSTEM_DISK` environment variable instead of `FILAMENT_FILESYSTEM_DISK` when uploading files. Laravel also uses this environment variable to represent the default filesystem disk, so this change aims to bring Filament in line to avoid potential confusion.
