Dramatiq abort v1.2.1

[dpgraham4401]

Description

This PR does the following:

1. Removes support for python 3.7
   • removes 3.7 from tox, github actions, project meta data
   • bumps configs that used python 3.7 as their reference (i.e., mypy)
2. Adds support for python 3.11 and 3.12
   • Adds versions to tox, github actions, project meta data
   • updates select type annotations to work with python 3.12 instead of 3.7
3. Adds a random actor_name keyword in the test_abortable_configs test.
   If tested against dramatiq==1.17.1, the current parameterized cases will all fail except for the first one because, the new version of dramatiq with throw the following exception from the Actor init method.

   ValueError: An actor named 'actor' is already registered.

   The previous version (1.16.0) did not include this check in the init method.
   To avoid that, generate a random string form actor_name to give the test/mock actor function a different name in each test scenario.
4. Increment dramatiq-abort's patch version to 1.2.1
5. Adds a py.typed file and includes it in the build artifact to indicate the downstream users that this package is typed
