[BUG] before_event, after_event can not trigger about beanie HOT 2 CLOSED

Hi @hd10180 ,
Thank you for the issue. Please use event Save for this case. Save and SaveChanges are different and use different events.

import asyncio
from datetime import datetime

from beanie import (
    Document,
    Insert,
    Replace,
    SaveChanges,
    Save,
    after_event,
    before_event,
    init_beanie,
)
from motor.motor_asyncio import AsyncIOMotorClient
from pydantic import BaseModel, Field


class Users(Document):
    name: str
    enabled: bool = True
    desc: str | None = None
    created: datetime = Field(default_factory=datetime.utcnow)

    # !附加检查
    @before_event([Insert, Replace, SaveChanges, Save])
    def checker_before(self):
        print("before..............")
        if not self.desc:
            del self.desc

    @after_event([Insert, Replace, SaveChanges, Save])
    def checker(self):
        print("after...............")
        if not self.desc:
            del self.desc

    class Settings:
        name = "users"
        use_state_management = True


class UpdateUsers(BaseModel):
    enabled: bool | None = None
    desc: str | None = None


async def main():
    import beanie

    print(f"beanie version: {beanie.__version__}")
    cli = AsyncIOMotorClient("mongodb://beanie:beanie@localhost:27017")
    db = cli["test_wrong_collection"]
    await db.drop_collection(Users.Settings.name)
    await db[Users.Settings.name].insert_one(
