ci: update GOOGLE_PLAY_JSON_PATH and workflow

The environment variable `GOOGLE_PLAY_JSON_PATH` is renamed to `GOOGLE_PLAY_JSON` and its value is updated.

The GitHub Actions workflow is updated to:
- Use the new `GOOGLE_PLAY_JSON` environment variable when creating the Google Service Account JSON file.
- Upload the `GOOGLE_PLAY_JSON` file as an artifact.
- Add a step to move the JSON file to the `app/` directory before building the AAB.
