Publish store screenshots from the repo on each stable release (#8186)

* feat(release): publish store screenshots from the repo

Stable releases now upload the committed store renders: the App Store
review lane attaches the iPhone and iPad sets to the version it submits,
and a new Play lane replaces the phone and tablet screenshots after the
Android submit. F-Droid reads the same Android files, which now link to
the store renders instead of the website images.

The Play lane needs its own copy of the submit service-account key
(GOOGLE_PLAY_JSON_KEY in the EAS production environment) because the key
Expo stores for eas submit is not available to custom jobs, and EAS
Metadata does not handle screenshots for either store.

* fix(release): rewrite the Android screenshot links on every render

Google Play and F-Droid read numbered links to the Google renders. The
renderer now rewrites them from the panels it exported, so adding or
renaming a panel reaches all three stores.
