Properly report Integration Test results on Dependabot PRs

The workflow step that publishes the integration test results to the PR as a comment + check, is skipped for dependabot triggered builds (because dependabot triggered builds have restricted permissions and the step would fail if it wasn't skipped).

We could fix this by doing the same thing we do for unit test results, where we have the subsequent Publish Test Results build that handles the publishing of the comment + check.
