Disable SDK telemetry in CI workflows (#105)

* Disable SDK telemetry in CI workflows

Set DO_NOT_TRACK=1 to prevent unit tests from firing
telemetry pings to the checkpoint endpoint. Each test
creates a new SDK client, generating thousands of pings
per CI run.

* Add DO_NOT_TRACK=1 to release workflow

Prevents telemetry pings during release test runs.
