API Query doctest fails due to different timezone representation

[agware]

Expected behaviour

The API query doctest should pass where the timezone is UTC regardless of representation

Actual behaviour

The doctest fails due to a returned representation of datetime.timezone.utc instead of <UTC>

Steps to reproduce the behaviour

Run ./datacube/api/query.py::datacube.api.query.Query.__init__ in local environment. Test passes when run --with-docker

>>> query.search_terms['time']  # doctest: +NORMALIZE_WHITESPACE
Expected:
    Range(begin=datetime.datetime(2001, 1, 1, 0, 0, tzinfo=<UTC>),         end=datetime.datetime(2002, 1, 1, 23, 59, 59, 999999, tzinfo=tzutc()))
Got:
    Range(begin=datetime.datetime(2001, 1, 1, 0, 0, tzinfo=datetime.timezone.utc), end=datetime.datetime(2002, 1, 1, 23, 59, 59, 999999, tzinfo=tzutc()))
