fix(integ-tests): use transformToString on API call response body (#27122)
This PR fixes an issue where our assertions handler will fail when logging the response of an API call if the response body is a Blob. Specifically, the following error is thrown: ``` Converting circular structure to JSON --> starting at object with constructor 'TLSSocket' | property 'parser' -> object with constructor 'HTTPParser' --- property 'socket' closes the circle (RequestId: 50c1b6cd-47d2-494f-baf1-d22646cd4e5f) ``` The fix for this issue was to call the `transformToString` method on the response body. This is mentioned in aws-sdk-js-v3 [`UPGRADE.md`](https://github.com/aws/aws-sdk-js-v3/blob/main/UPGRADING.md?plain=1#L573-L576) as the solution for `Lambda::Invoke`. Its unclear why `S3::GetObject` isn't mentioned as well, but it works for that too. However, instead of explicitly extracting the `Body` property from a response, we now recursively traverse the response and detect any such blob types that should be converted to strings - this should protect us against any other APIs that may exhibit this behavior. > `transformToString` is implemented as part of the [`SdkStreamMixin` interface](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/Package/-smithy-types/Interface/SdkStreamMixin/). Included in this PR is a fix for `aws-s3-deployment/test/integ.bucket-deployment-substitution.ts` which was previously failing with the error shown above.
