chore(telemetry): telemetry error logs are now constant (#13781)

The current goal is to limit at maximum the risk of sending any PII into
telemetry.
A proposition will soon be done to be able to send custom messages while
still ensuring safety. In the meantime, only constant messages will be
sent to telemetry.
