Update to support Django versions < 5.0

[Afani97]

• Update django to latest 4.2 version
• Set a max version allowed for smpplib until a bug fix PR has been merged, noted in the toml file.
• Update pre-commit file to include django-upgrade

RapidSMS might need to be upgraded, it seems to be crashing this build: https://github.com/caktus/rapidsms-smpp-gateway/actions/runs/5581453954/jobs/10199938046?pr=16#step:6:67

In addition to the rapidsms fix, it could be worth adding tox to this repo, to test against both Django 3.2 and 4.2 (and different versions of Python). See django_bread for an example.

Looks good. Maybe changes.md should be updated with release notes?

[ronardcaktus]

How would you feel about updating other hooks? flake8, isort, etc to the latest version?

[Afani97]

That sounds good to me, I'll see what I can do.

Python 3.9 is failing in Github actions with the following error:

  File "/home/runner/.cache/pypoetry/virtualenvs/smpp-gateway-28Xge_hh-py3.10/lib/python3.10/site-packages/rapidsms/templatetags/paginator_tags.py", line 19, in <module>
    if "django.template.context_processors.request" not in settings.TEMPLATES[0]['OPTIONS']['context_processors']:
IndexError: list index out of range

However, settings.TEMPLATES[0]["OPTIONS"]["context_processors"] is in the code. I did some local testing:

(Pdb) settings.TEMPLATES[0]["OPTIONS"]["context_processors"]
['django.contrib.auth.context_processors.auth', 'django.template.context_processors.debug', 
'django.template.context_processors.i18n', 'django.template.context_processors.media', 'django.template.context_processors.static', 'django.template.context_processors.tz', 'django.contrib.messages.context_processors.messages', 'django.template.context_processors.request']

(Pdb) "django.template.context_processors.request" in settings.TEMPLATES[0]["OPTIONS"]["context_processors"]
True

Yes, this PR depends on RapidSMS being updated to support Django 4.2 then this should go away. But the PR for that upgrade is failing for 3.10 for some odd reason.
