feat: add create_collection function to MongoHook

[nailo2c]

Closes: #33076

This PR adds a create_collection() function to the MongoHook which refers to pymongo.database.Database.create_collection.

Before:

mongo_hook = MongoHook(conn_id="mongo_default")
mongo_conn = mongo_hook.get_conn()
mongo_db = mongo_conn["db_name"]

# create time collection here
mongo_db.create_collection("time_test", timeseries= {
    "timeField": "timestamp",
    "metaField": "metadata",
    "granularity": "hours"
})

# use the collection
mongo_collection = mongo_db["time_test"]

# add document
mongo_collection.insert_one(
  {
    "metadata": { "sensorId": 5578, "type": "temperature" },
    "timestamp": dt.utcnow(),
    "temp": 12
  }
)

After:

mongo_hook = MongoHook(conn_id="mongo_default")

# create (or get) the time-series collection in one call
mongo_collection = mongo_hook.create_collection(
    name="time_test",
    timeseries={
        "timeField": "timestamp",
        "metaField": "metadata",
        "granularity": "hours",
    },
)

# add document
mongo_collection.insert_one(
    {
        "metadata": {"sensorId": 5578, "type": "temperature"},
        "timestamp": dt.utcnow(),
        "temp": 12,
    }
)

I’ve completed an end-to-end test on my local Airflow instance, and everything worked as expected.
