Description

Fixed error overlapping when validation error is caused by remove_unset root validator in base types and methods.

Example:

InlineKeyboardButton(
    text="Play with Friends",
    switch_inline_query_chosen_chat="test",
)

Caused:

  .../aiogram/types/base.py", line 31, in remove_unset
    return {k: v for k, v in values.items() if not isinstance(v, UNSET_TYPE)}
AttributeError: 'str' object has no attribute 'items'                                                                                                                      

Expected:

pydantic_core._pydantic_core.ValidationError: 1 validation error for InlineKeyboardButton
switch_inline_query_chosen_chat
  Input should be a valid dictionary or instance of SwitchInlineQueryChosenChat [type=model_type, input_value='test', input_type=str]
