When using the autofixer for `Q000` it does not remove the backslashes
from quotes that no longer need escaping.
This new rule checks for such backslashes (regardless whether they come
from the autofixer or not) and can remove them.

## Summary
The markdown documentation was present, but in the wrong place, so was
not displaying on the website. I moved it and added some references.
Related to #2646.
## Test Plan
`python scripts/check_docs_formatted.py`
## Summary
Fix CI (broken in #7496).
The code snippet was formatted as Black would format a stub file, but
the CI script doesn't know that (it assumes all code snippets are
non-stub files). Easier to ignore.
Sorry for breaking CI!
## Test Plan
`python scripts/check_docs_formatted.py`
Adds rule to convert type aliases defined with annotations i.e. `x:
TypeAlias = int` to the new PEP-695 syntax e.g. `type x = int`.
Does not support using new generic syntax for type variables, will be
addressed in a follow-up.
Added as part of pyupgrade — ~the code 100 as chosen to avoid collision
with real pyupgrade codes~.
Part of #4617
Builds on #5062
## Summary
This PR implements pycodestyle's E241 (tab after comma) and E242
(multiple whitespace after comma) lints.
These are marked as nursery rules like many other pycodestyle rules.
Refs #2402
## Test Plan
E24.py copied from pycodestyle.
**Summary**
Updated doc comments for `missing_whitespace_around_operator.rs`. Online
docs also benefit from this update.

## Summary
This is an error message only change to lead an implementor of a new
rule that has an unformatted or invalid bad example to the
right code.

## Summary
Adds `PERF401` and `PERF402` mirroring `W8401` and `W8402` from
https://github.com/tonybaloney/perflint
Implementation is not super smart but should be at parity with upstream
implementation judging by:
c07391c176/perflint/comprehension_checker.py (L42-L73)
It essentially checks:
- If the body of a for-loop is just one statement
- If that statement is an `if` and the if-statement contains a call to
`append()` we flag `PERF401` and suggest a list comprehension
- If that statement is a plain call to `append()` or `insert()` we flag
`PERF402` and suggest `list()` or `list.copy()`
I've set the violation to only flag the first append call in a long
`if-else` statement for `PERF401`. Happy to change this to some other
location or make it multiple violations if that makes more sense.
## Test Plan
Fixtures were added with the relevant scenarios for both rules

## Summary
Add documentation to the `D3XX` rules that check for issues with
docstring quotes. Related to #2646.
