arrow 1.2.3 doesn't run under Python 3.11

[tammyalexandra]

Issue Description

arrow 1.3.2 no longer works under Python 3.11 due to its dependency on python-datetime-tz.

When I try to start up a web server, the import arrow call fails:

> python manage.py runserver
Exception in thread django-main-thread:
Traceback (most recent call last):
...
  File "/Users/.../.../models.py", line 1, in <module>
    import arrow
  File "/usr/local/lib/python3.11/site-packages/arrow/__init__.py", line 2, in <module>
    from .api import get, now, utcnow
  File "/usr/local/lib/python3.11/site-packages/arrow/api.py", line 12, in <module>
    from arrow.arrow import TZ_EXPR, Arrow
  File "/usr/local/lib/python3.11/site-packages/arrow/arrow.py", line 32, in <module>
    from dateutil import tz as dateutil_tz
  File "/usr/local/lib/python3.11/site-packages/dateutil/tz.py", line 78
    `self._name`,
    ^
SyntaxError: invalid syntax

When I try to reinstall arrow to update the dependencies, it fails as follows:

> pip install arrow
Requirement already satisfied: arrow in /usr/local/lib/python3.11/site-packages (1.2.3)
Requirement already satisfied: python-dateutil>=2.7.0 in /usr/local/lib/python3.11/site-packages (from arrow) (2.8.2)
Requirement already satisfied: six>=1.5 in /usr/local/lib/python3.11/site-packages (from python-dateutil>=2.7.0->arrow) (1.9.0)
DEPRECATION: python-datetime-tz 0.5.4 has a non-standard dependency specifier pytz>=2011g. pip 23.3 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of python-datetime-tz or contact the author to suggest that they release a version with a conforming dependency specifiers. Discussion can be found at https://github.com/pypa/pip/issues/12063

Thanks for looking into this.
