austinried af3741a549 ci: share the build and isolate the release credentials
Extract checkout, nix, signing and the Gradle run into a reusable build
workflow used by CI, the next build and the release build job. The build
job holds only the signing secrets; the publish job is the only one with
a write token and the Play credential. The Play service account is now
written to a 0600 file and passed via --json_key instead of on argv.
