Remove telemetry debounce time in zed 2 (#3809)

Remove the event send timer in Zed 2 telemetry in effort to continue
reducing the amount of stress the vercel endpoint receives. This allows
the queues to fill up entirely before sending them off. I'm leaving the
timer in for Zed 1 because we don't force the events queue to clear on
app close in Zed 1, so it feels best to leave it in there, as it might
catch some unsent events before closing.

Release Notes:

- N/A
