Cancels BuildKite scheduled builds via its API (to clear a backlog due to offline agents and just focus on new builds)

You might have to run this more than once if there are a lot of scheduled builds due to limitations with BuildKite's
API pagination not returning all results or even indicating if there are more results to return
