Include prediction ID on edit prediction accepted/discarded events (#24480)

This PR updates the edit predictions to include the prediction ID
returned from the server on the resulting telemetry events indicating
whether the prediction was accepted or discarded.

The `prediction_id` on the events can then be correlated with the
`request_id` on the server-side prediction events.

Release Notes:

- N/A
