test(maintenance): improve assertions on traces & logs

[dreamorosi]

Summary

Changes

Please provide a summary of what's being changed

This PR improves and simplifies the helpers used to retrieve AWS X-Ray trace data that are used in the integration tests. As a result of this, the integration tests for the utility are also slightly simplified due to the helpers handling more of the data retrieval & validation from the X-Ray API.

The PR also extends some assertions in the Idempotency tests to more flexibly assert timeouts in Amazon CloudWatch Logs.

While working on this, I have also updated the Dependabot config so that it targets the @aws-cdk/cli-lib-alpha (dependency of packages/testing) as it had fallen behind on updates and was no longer compatible with the more recent AWS CDK installed version.

Great work. The code duplication is a bit high for all the tracer tests (middy, decorator, manual), but I think we can address it in a different PR. We have many such cases where we need to check the same outcomes for various setups.

I agree. We have upcoming PRs where we'll work on streamlining similar to what we did in other areas in the past few weeks. For now seeing as the PR was already large I decided to not act on this.
