Scheduled pipelines set to 'manual' don't run

When you have a CI job that is set to run manually, and create a schedule to run the pipeline, the manual job is created but not run.

There is something to be said for that, as the schedule is not a manual trigger per se, but I think that it's mostly counter-intuitive. Either scheduled runs should be treated as manual runs or (probably nicer) when: could have an option to also trigger on schedules, maybe like so:

when:
  - manual
  - schedules
