Added support for Django 4.2

Replaced the `index_together` model Meta option with `indexes` in
`simple_history/models.py`, as the former has been deprecated (see
https://docs.djangoproject.com/en/4.2/releases/4.2/#index-together-option-is-deprecated-in-favor-of-indexes).
(This option has existed since before Django 3.2 - the minimum version
we support.)
