### What you expected to see, versus what you actually saw

In PR https://github.com/risingwavelabs/risingwave/pull/11679

Part of `aws-*` are updated. I expect to update all of them.

This also caused multiple versions of the dependencies occuring.

Start with the linked .github/dependabot.yml configuration and PR #11679, then trace how the Cargo ecosystem handles the aws-* dependency group. Reproduce the missed updates and multiple versions if possible; done means the group updates all expected aws-* dependencies without leaving duplicate versions.
