Do we need to update the aws sdk packages dep versions for liveness?

Do we need to update the aws sdk packages dep versions for liveness?

I don't think so, because the "@smithy/util-base64@^2.0.0": is what the aws sdk packages reference, and that got updated to 2.2.1 @calebpollman

@aws-amplify/ui-react-liveness@3.0.13 -> ./packages/react-liveness
  ├─┬ @aws-sdk/client-rekognitionstreaming@3.398.0
  │ ├─┬ @aws-sdk/client-sts@3.398.0

I think for good measure, we might as well update @aws-sdk/client-rekognitionstreaming as well

[calebpollman]

Can you update the following dep versions in the liveness package.json:

• @aws-sdk/client-rekognitionstreaming
• @aws-sdk/util-format-url
• @smithy/eventstream-serde-browser
• @smithy/fetch-http-handler
• @smithy/protocol-http

[calebpollman]

Can we investigate what's happening here?
