fix(telemetry): disable for unofficial environments (#7482)

On the one hand, learning about in which edgecases our software fails is
useful and thus having telemetry also active for self-hosted users is
beneficial. On the other hand, we have neither control nor a contact to
those self-hosted and whatever they are doing might spam our Sentry
account with errors that we can't do anything about.

To mitigate this, we disable telemetry for self-hosted users with the
next release.

Once we have more resources, we can consider enabling this again.
