Drop Play Console upload from the Release workflow

The Release-* workflow now only builds Noo-<version>.aab and attaches it to
the Gitea release. The now-unused upload script is removed with it.

-"""Uploads an .aab to the Play Console's app bundle library, without
-touching any release track.
-
-Play Console itself doesn't expose "just upload, don't release" as an
-action - every path through the UI attaches a bundle to a track. The Play
-Developer API does support it though: open an edit, upload the bundle,
-commit the edit, and stop there. The result shows up under Release > App
-bundle explorer and nowhere else - nothing goes out to testers or
-production until it's promoted to a track by hand, whenever that's wanted.
-
-Needs:
-  GOOGLE_PLAY_PACKAGE_NAME             e.g. dev.ayushya.noo
-  GOOGLE_PLAY_SERVICE_ACCOUNT_JSON_PATH  path to a service account key file
-
-The Play Developer API can't create an app's first release - Google
-requires at least one manual upload through the Play Console web UI (to
-any track) before it'll accept API calls for that app at all.
