fix(keep alive): Shorten the time before API call (#31)

* fix: Shorten the time before API call

The current 55 day timeout before we hit the API seems to be a little long, as GitHub warns before 55 days. We can shorten it, here to 45.

But I'm not sure why we don't just use `1` here instead, not sure it would do any harm to hit the API daily.
