fix(jobs): increase retry delay to be greater than timeout

> The --timeout value should always be at least several seconds shorter than your retry_after configuration value. This will ensure that a worker processing a given job is always killed before the job is retried. If your --timeout option is longer than your retry_after configuration value, your jobs may be processed twice.
