Allow to set some tolerance for the dispatch-date query

[crivetechie]

Is your feature request related to a problem? Please describe.

For the past month this action has started failing to detect triggered workflows, the issue is with the fact that the dispatch-date stored by the action is older than the start date of the workflow (off by 1 second), this is likely caused by servers not having the time synchronised.

Describe the solution you'd like
Provide an input allowing to set tolerance in seconds so that instead of filtering workflows with start-date >= dispatch-date it queries by start-date >= dispatch-date - tolerance
