Bump patch version for `aws-config` (#3516)

Precommit hooks and CI have started failing due to `runtime-versioner`
reporting `aws-config` requires a version bump.

While the most recent change to that crate was made by [this
PR](https://github.com/smithy-lang/smithy-rs/pull/3491) only updating
test-related code, it does still require a version bump.
