* Add serialization utilities and update documentation
Introduced utilities to deserialize Telegram objects to JSON-compliant Python objects and vice versa. These utilities manage both cases with and without files. The documentation has been updated to reflect these changes, including updates in migration recommendations and tutorials. A new unit test is added to verify the new functionality.
* Fixed Must-die implementation of the datetime serialization
* Fixed `TypeError: can't subtract offset-naive and offset-aware datetimes`
Implemented a MediaGroupBuilder class in 'aiogram/utils/media_group.py' to help construct media groups. The class supports addition of different media types (audio, photo, video, document) to the media group with a maximum limit of 10 files. The functionality is demonstrated and usage is documented in 'docs/utils/media_group.rst'. Added related test cases in 'tests/test_utils/test_media_group.py'. This is to streamline and simplify the process of media group creation
