deps: Upgrade packages to latest, namely package_info_plus

This is the result of `flutter pub upgrade --major-versions`.

(Plus `flutter build ios --config-only`
and `flutter build macos --config-only`, but those had no
effect.)

Changelog:
  https://pub.dev/packages/package_info_plus/changelog

Nothing there that affects us.
