With Triggers a user can invoke a Lambda Function during every stack deployment.

When we migrated the handler code to SDKv3, we overlooked that the return payload from the invoked lambda function is now a Uint8Array, and not a string anymore.
In the error case, we attempt to JSON.parse() the error payload which then resulted in a list of bytes being returned to the user.

Updated the handler test case to use correct mocks, including returning a payload that is a Uint8Array.

Closes #27113

Added pr-linter/exempt-integ-test label because this is the unhappy path and we can't test this right now.
