Every class should be imported from wechaty repo

[wj-Mcat]

Describe the bug
As described in : https://github.com/wechaty/wechaty.js.org/pull/684#discussion_r588297559

There are some class that are also imported from wechaty-puppet package, so we should fix them.

To Reproduce

• example code:

from wechaty import Wechaty
from wechaty_puppet import EventReadyPayload
import asyncio

# method one
async def on_ready(payload: EventReadyPayload):
    """Any initialization work can be put in here
    Args:
        payload (EventReadyPayload): ready data
    """
    print(f'receive ready event<{payload}>')

bot = Wechaty()
bot.on('ready', on_ready)
asyncio.run(bot.start())

# method two (suggested)

class MyBot(Wechaty):
    async def on_ready(self, payload: EventReadyPayload):
        """Any initialization work can be put in here
        Args:
            payload (EventReadyPayload): ready data
        """
        print(f'receive ready event<{payload}>')
        
asyncio.run(MyBot().start())

We should keep ths
