[cdk-pipelines] Manual approval steps are not getting the right RunOrder

[JFox]

When using pipeline.addAdpplicationStage({manualApprovals: true}) the resulting RunOrder for the actions is causing the deploys to be performed without waiting for the manual action to be done

Reproduction Steps

    pipeline.addApplicationStage(
      new WorkloadAccountApplication(this, 'WorkloadAccount', {
        env: { account: '1111111111', region: 'eu-central-1' },
      }),
      {
        manualApprovals: true,
      },
    );

This is 🐛 Bug Report

[roskelleycj]

When I tried this:

    const prodStage = pipeline.addApplicationStage(prod);
    prodStage.addActions(new ManualApprovalAction({
        actionName: 'ApproveChanges'
    }));

This at least put the manualApproval BEFORE the execution of Deploy. However, it also put it with the same runOrder as the Prepare, which is also undesirable, IMHO. It would be ideal to have this:

Myservice.Prepare -> ManualApproval -> Myservice.Deploy

Thus allowing for the human reviewer to inspect the ChangeSet after it is completed AND before making the approval to do the Deploy.
