Provide update schematics for google-maps and youtube-player package

[Akxe]

Reproduction

Steps to reproduce:

1. Have an Angular 9 app
2. Update to Angular 10

Expected Behavior

Either https://update.angular.io/#9.0:10.0l3 should inform that it needs to be updated manually too, or it should update with @angualr/material.

Actual Behavior

Did only update @angular/material and @angular/cdk.

Environment

• Angular:
• CDK/Material: 9 => 10
• Browser(s): ---
• Operating System (e.g. Windows, macOS, Ubuntu): Windows

I'd say that this works as expected since @anguar/google-maps isn't related to @angular/material and @angular/cdk, apart from being in the same repository. I suppose we could provide ng update support for the Google Maps package specifically.

It wasn't really hard to upgrade it manually, but since there are breaking changes, I had to go through my code to fix them manually. Either an automatic update or a list of changes to look for after updating would be nice.

Yeah, it works as expected that ng update @angular/material does not update the youtube-player or google-maps package as those are separate unrelated packages. I agree though that we should probably set up update schematics for those packages if there are breaking changes.

I can understand why ng update @angular/material does not update other, but the update.angular.io should have a note about updating these
