prepare_for_embedded.dart should use a fixed Cronet version

[brianquinlan]

prepare_for_embedded.dart updates build.gradle to use the latest version of Cronet.

This leads to the possible problem that the version of Cronet included in a release may not have been tested.

Instead, we should set an explicit version in prepare_for_embedded.dart.

Any thoughts about this @AlexV525 ?

[AlexV525]

It should be a corresponding version of the GMS version. Is the dependabot be able to do this?

[brianquinlan]

Do the GMS and embedded versions track identically? If so, we can just replace "com.google.android.gms:play-services-cronet" with "org.chromium.net:cronet-embedded" in prepare_for_embedded.dart and leave the version unchanged.

Unfortunately no

I don't know the answer regarding dependabot.

[AlexV525]

Well that is just my idea. I'll do some investigation about it, before that we can find the correct version and apply it first.

@brianquinlan Are you able contact owners of Cronet to know about version mapping between GMS and non-GMS versions?
