## Motivation and Context
<!-- Why is this change required? What problem does it solve? -->
<!-- If it fixes an open issue, please link to the issue here -->
Fix canary install dependencies step that is
[failing](https://github.com/awslabs/aws-sdk-rust/actions/runs/12898260366/job/35965110537)

```
Package awscli is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'awscli' has no installation candidate
```

AWS CLI is installed by default on ubuntu runners. See
[runner-images](https://github.com/actions/runner-images). It appears
`ubuntu-latest` recently switched from 22.04 to 24.04 which may be what
caused this to stop working.
