Hi! I'm getting this DeprecationWarning when using tqdm with Python 3.12.

~\venv\Lib\site-packages\tqdm\std.py:580: DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC).
    if rate and total else datetime.utcfromtimestamp(0))

I'm guessing changing this LOC to:

    if rate and total else datetime.fromtimestamp(0, timezone.UTC)

Should fix the warning.

Let me know if it would help for me to open a PR with the change.

Thanks!
