'QbittorrentManager' object does not support the context manager protocol during torrent finish event

[rlyalchenko]

Hi,

I've just got the following error in log, when the bot tried to notify about a completed downlod.

Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/apscheduler/executors/base_py3.py", line 30, in run_coroutine_job
    retval = await job.func(*job.args, **job.kwargs)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/app/src/utils.py", line 15, in torrent_finished
    with QbittorrentManager() as qb:
TypeError: 'QbittorrentManager' object does not support the context manager protocol

I'm using the latest image from Docker hub.
