Describe the solution you'd like
A clear and concise description of what you want to happen. Ex. It would be great if [...]

It would be nice to silence these until we can fix them either by settings.py:

import warnings

warnings.filterwarnings(
    "ignore",
    message="DateTimeField .* received a naive datetime",
    category=RuntimeWarning,
    module='django.db.models.fields',
)

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

• we could subclass the testrunner SuppressingSpamyWarningsTestRunner but that seems like a lot of repetition across all tests/ dirs.

Instead of silencing, I tried solving it here: #2601
