PoC: Bot instance inside method shortcuts using pydantic Validation Context (#1210)

* PoC: Mount objects to the Bot instance, bind shortcuts to configured instance

* Fixe docstring of the bind method

* Pass Bot instance explicitly to the URLInputFile

* Added tests

* Added changelog

* Refactor aiogram client and update tests

Refactored base.py to improve code readability by separating response_type operation from model_validate(). Also, adjusted the parameters in URLInputFile() within test_input_file.py for better test coverage. Updated input_file.py to streamline read method and avoid unnecessary instantiation of Bot class. Lastly, adjusted typing in methods/base.py to enhance code clarity.

* Update changelog
