• I have searched in the issue tracker for similar bug reports, including closed ones

Operating system

Manjaro

Python version

3.10.x

aiogram version

3.0b4

Expected behavior

According to the documentation, you can pass arbitrary kwargs to Dispatcher's constructor.

Current behavior

Apparently, that's not possible. The code below results in the following error:

Traceback (most recent call last):
  File "/home/groosha/PycharmProjects/aiogram-3.x-playground/bot.py", line 6, in <module>
    dp = Dispatcher(another="hello")
  File "/home/groosha/PycharmProjects/aiogram-3.x-playground/venv/lib/python3.10/site-packages/aiogram/dispatcher/dispatcher.py", line 52, in __init__
    super(Dispatcher, self).__init__(**kwargs)
TypeError: Router.__init__() got an unexpected keyword argument 'another'

Steps to reproduce

1. Run the code below

Code example

import asyncio
from aiogram import Bot, Dispatcher

bot = Bot(token="TOKEN")
dp = Dispatcher(another="hello")

async def main():
    await dp.start_polling(bot)

if __name__ == "__main__":
    asyncio.run(main())

Logs
