Remove unused `statuspageio` dependency

[jamesrwhite]

• It appears to be unused and the upstream project is seemingly unmaintained (not updated since 2016)
• It also blocks installs when using versions of setuptools > 57.5.0 due to the same issue described in: https://github.com/tikitu/jsmin/issues/33

You can re-create the issue with installing like so (tested with Python 3.9.7):

mkdir test && cd test
pip install poetry
poetry init --no-interaction
poetry add django-incident-response

Output:

Using version ^0.5.1 for django-incident-response
