Update django-cors-headers to 3.5.0

[pyup-bot]

This PR updates django-cors-headers from 3.4.0 to 3.5.0.

Changelog

3.5.0

------------------

* Following Django’s example in
`Ticket 31670 <https://code.djangoproject.com/ticket/31670>`__ for replacing
the term “whitelist”, plus an aim to make the setting names more
comprehensible, the following settings have been renamed:

* ``CORS_ORIGIN_WHITELIST`` -> ``CORS_ALLOWED_ORIGINS``
* ``CORS_ORIGIN_WHITELIST_REGEX`` -> ``CORS_ALLOWED_ORIGIN_REGEXES``
* ``CORS_ORIGIN_ALLOW_ALL`` -> ``CORS_ALLOW_ALL_ORIGINS``

The old names will continue to work as aliases, with the new ones taking
precedence.
