Update build system to insert Rudder keys in release and RC builds as appropriate.

Description

At the moment, the build system inserts Segment keys into release builds. We should update it to also insert Rudder keys so that data gets sent to Rudder.

Need to confirm whether the keys should be set for release builds only, as with segment, or also for RC builds, to facilitate testing?
