Moves version to PulpPluginAppConfig subclass

Starting with pulpcore==3.9, it's expected for the version of a plugin
to be set as the `version` attribute on the `PulpPluginAppConfig`
subclass which defines the plugin.

This also updates the bumpversion config to set versions in the right
places, and the release script to now parse those locations correctly.

+Moved the version definition to the ``version`` attribute of ``PulpPluginAppConfig``, and have
+``bump2version`` maintain it. Also update the ``docs/conf.py`` to be bump2version maintained. The
+release script now parses its versions from ``setup.py`` which is needed for the removal of
+``{plugin_name}.__init__.__version__``.
