app: pin ascAppId in the submit profile for non-interactive --auto-submit

eas-cli can only resolve the App Store Connect app id interactively;
the CI trigger runs --non-interactive and failed at submission setup
("Set ascAppId in the submit profile"). Looked up via the ASC API for
bundle app.sidecode.
