🗑️ Refactor Meetup model by removing unused $fillable fields and updating dependencies in composer.lock

- Removed unnecessary `city_id` and `created_by` attributes from `Meetup` model.
- Updated multiple dependencies in `composer.lock`, including `guzzlehttp/guzzle`, `laravel/framework`, and other libraries to the latest versions.
- Verified all updates maintain compatibility with existing functionality.
