Consider preferring preferred quote style if both styles require backslashes

[charliermarsh]

Given:

"json enter input={'a': 2} kwargs={\"strict\": None, \"context\": {\"c\": 2}}"

Black will reformat as:

'json enter input={\'a\': 2} kwargs={"strict": None, "context": {"c": 2}}'

Ruff does the same thing, so it's not a compatibility issue. But I'm wondering if it makes more sense to bias towards the preferred quote style if you need backslashes regardless (even if the non-preferred style results in fewer backslashes).

This came up in the Pydantic migration: https://github.com/pydantic/pydantic/pull/7930/files#r1373829517

I'm leaning toward Black compatibility. It doesn't seem we have strong reasoning to diverge. E.g. for the above example, I find Black's formatting easier to read and it results in a shorter string overall.

"json enter input={'a': 2} kwargs={\"strict\": None, \"context\": {\"c\": 2}}"

It doesn't seem to have come up again. We can improve our documentation if this comes up more often. @charliermarsh feel free to re-open if you disagree with my decision.
