plugins.dart's _getAndroidEmbeddingVersion() isn't strictly right for module types. The embedding version is determined by the AndroidManifest of the app but modules' embedding version should just be hardcoded to V2. The modules happens to have a lightweight wrapper app as an example whose AndroidManifest says v2 but it's more of a coincidence.

We should probably fix it at the same time as #44245
