axum: 0.7.9 → 0.8.1

Some breaking changes. For better or for worse. The optional extractor
breaking change is a double-edged sword, since not all extractors can
be used with `Option<T>` now, and you have to use
`Result<T, T::Rejection>` even when you want to ignore an error coming
from an extractor, such as `Query`.

However, this allows catching errors on authorization extractors even
in places where authorization is optional.
