feat(android): Update SAGP to 6.2.0-alpha.2 and upload roborazzi snapshots to Sentry (#756)

## Summary

- Bumps the Sentry Android Gradle Plugin to `6.2.0-alpha.2`
- Configures `sentry.snapshots` with the app ID and roborazzi output
path (`build/outputs/roborazzi`)
- Adds `sentryUploadSnapshots` to the roborazzi CI job so snapshots are
uploaded to Sentry after `recordRoborazziDebug` generates them
