Re-use the existing bundle steps for nightly too (#41699)

One of the reasons we didn't spot that we were missing the telemetry env
vars for the production builds was that nightly (which was working) had
its own set of build steps. This re-uses those and pushes the env vars
down from the workflow to the job.

It also fixes nightly releases to upload all-in-one go so that all
platforms update in sync.

Closes #41655
