## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Part of #18972
This PR makes [docstring-missing-exception
(DOC501)](https://docs.astral.sh/ruff/rules/docstring-missing-exception/#docstring-missing-exception-doc501)'s
example error out-of-the-box. Since the exceptions in the function body
need to undergo name resolution to figure out if one of them is
`NotImplementedError`, `DOC501` won't lint if the raised name is not
defined. This could be considered a limitation, but should be fine since
`F821` already covers undefined names. I did discover a different edge
case, but it's not relevant to the example.
[Old example](https://play.ruff.rs/d213e87d-e5c7-49d8-a908-931f61f06055)
```py
def calculate_speed(distance: float, time: float) -> float:
"""Calculate speed as distance divided by time.
Args:
distance: Distance traveled.
time: Time spent traveling.
Returns:
Speed as distance divided by time.
"""
try:
return distance / time
except ZeroDivisionError as exc:
raise FasterThanLightError from exc
```
[New example](https://play.ruff.rs/cb41e0b7-b950-4fa0-842d-cecab9c8e842)
```py
class FasterThanLightError(ArithmeticError): ...
def calculate_speed(distance: float, time: float) -> float:
"""Calculate speed as distance divided by time.
Args:
distance: Distance traveled.
time: Time spent traveling.
Returns:
Speed as distance divided by time.
"""
try:
return distance / time
except ZeroDivisionError as exc:
raise FasterThanLightError from exc
```
The "Use instead" section was also updated similarly.
## Test Plan
