Use ruff format

[karpetrosyan]

Ruff introduced a new formatter that can completely replace black, allowing us to use ruff instead of ruff + black.

Ruff formatter, like ruff linter, is extremely fast.

This looks good to me.

Change to 88 back, please. At least let's discuss first.

Also, what's the time black takes to format httpx?

It was 120 originally, and I just reverted that change 😕 .

I don't think it matters; we just have an opportunity to get rid of the extra dependency.

It was 120 on linting... It was 88 on format.

How do you want me to do it? Both the formatter and the linter have a single line length. I'm not sure what the "change back to 88" even means here.

Setting the formatter line length equal to the linter line length feels more natural to me.

Okay, I used the solution that @T-256 suggested, which was to use the max-line-length provided by the pycodestyle settings to keep this pull request as simple as possible.

Later, I'll start a discussion about enforcing limits to the same number.
