…and All-Hands-AI#1100 with the hope to fix the inconsistent behaviour across linters and environments. However, we recently found out that double-quote-string-fixer plugin in pre-commit-hook has inconsistent behaviour on python 3.11 and 3.12. See discussion here. This is sad because while this plugin enforces single quote behaviour with 3.11, it doesn't always enforce so with 3.12. Specifically, with fstr syntax, this plugin allows both single quotes and double quotes with python 3.12.

The problem is, some developers have black linter installed/integrated with their IDE, which is probably the most popular linter in python world (ranked by GitHub stars). This linter insists on always using double quotes. Now we have black and double-quote-string-fixer fight each other (iff the developer uses python 3.12) for some quotes (fstr syntax).

After a lot of research, I couldn't find a way to enforce single quote behaviour without introducing a new dependency, flake8, together with a plugin for it to enforce quotes' behavior. I believe it's better off introducing the more popular black if we have to introduce a new linter. Since black and autopep8 sometimes fight each other, and they mostly overlap, I further remove autopep8.

The unfortunate consequence of this PR is that I had to revert all single quotes back to double quotes. This might cause some inconvenience to existing PRs as they have to resolve conflicts, but I believe the headache will be gone soon. That being said, I am open to abandon this PR if anyone has a better idea to solve the headache.
