support django 2.1+ test client json data automatically serialized

[terencehonles]

Description

• Support Django 2.1+ test client auto serializing data if the content type is a json type
• Ensure the result of _encode_data is always Tuple[bytes, str] rather than Tuple[Union[bytes,str], str]

[auvipy]

to have a better review need to add a test for the proposed change.

I'm definitely going to agree with @auvipy here. A test case demonstrating the behavior change would be required for this to be accepted.

My immediate reaction is "why aren't our tests failing under Django 2.1+?"

[terencehonles]

@rpkilby updated with a test

bumped, I think the failed test was unrelated but this re-run the test suite

[auvipy]

also, please rebase, and I think we might get rid of some checks to eleminate older version check

The failing test should be fixed by #9129

can you rebase? and check if any document or test update is needed to get this merged? also a reference to django docs related to this would be really helpful

It's mentioned here https://docs.djangoproject.com/en/4.2/topics/testing/tools/#django.test.Client.post (specifically), and it's mentioned in the 2.1 release notes https://docs.djangoproject.com/en/4.2/releases/2.1/#tests (point 2)

I'm not sure if you're asking for this to be included in the source, since there's not specifically a good place to put it (maybe the tests?), or if you're just asking for the release notes.
