fix(skytrace): suppress all warnings from Node.js

Temporary fix to suppress the following warning:

(node:72224) ExperimentalWarning: The Fetch API is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)

Which originates from one of the dependencies introduced by
adding telemetry.
