Update fastlane to upload APK straight to production to reduce wasted time on double reviews

Description

We experience lengthy Play Store reviews and pay the price twice for each release:

• one review is triggered when we upload our APK to the staging track
• a second review is triggered when we promote from staging to begin the production rollout

Each of the reviews can amount to many hours each. This PR changes it so that we skip staging and go straight to production at 0.01% rollout so that the review clock starts immediately and we only have to wait for a single app review instead of needlessly waiting on two for the same release.

Steps to test this PR

• [x] Sense-check the change. Can't really test until we next do a release.
