prlint: assess needs review after codebuild job succeeds

[kaizencc]

Describe the bug

We refuse to assess if a PR needs review if the codebuild job is not successful. However if the pr linter runs before the codebuild job is done, it will not run again until another triggering action happens on the PR. So a situation like this might happen:

1. open a PR
2. community approves
3. build reports successful

We would like this situation to still get labeled needs-maintainer-review after the build is successful, but instead it will not report anything until the next trigger.

Reproduction Steps

Possible Solution

We need the codebuild job to trigger the pr linter somehow. A possible solution is to modify the github workflow to trigger on issue_comment as well, and filter comments for the specific one that comes from aws-cdk-automation when the build succeeds. However, this likely opens prlinter to run on all prs and issues, albeit it will skip all jobs for non prs. That might be non tenable.

Alternatively, we can finangle the codebuild step to hit one of the PR triggers when successful, like adding a new label.
