[Synthetics] Update pings query to not use last 30 days time range !! (#208366)

## Summary

Fixes https://github.com/elastic/kibana/issues/198443 !!

Instead of using last 30 days, it will now uses last 24 hours otherwise
it will fall back to last 7 days and then last 30 days.

Last run should still work as expected
