## 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.
