feat!: release build defaults to aab package type

[erisu]

Motivation, Context & Description

This PR changes the default package type of the release builds to be aab (Android App Bundle). In August, AAB format is required for all new apps.

https://developer.android.com/distribute/play-policies#RequirementForNewApps

Exisiting apps can continue to release APK packages till November. To continue to build release APK, append the --packageType=apk flag to the build command.

Testing

• npm t
• Android build with command line

Checklist

• I've run the tests to see all new and existing tests pass
• I've updated the documentation if necessary

Hi @erisu,
you wrote: "To continue to build release APK, append the --buildType=apk flag to the build command."
Found out that "buildType" is responsible to build 'release' or 'debug'.
As i see 'packageType' is the right argument to set the package type.
And valid values are 'apk' and 'bundle' as defined in PackageType.js.

As a result, if i want an APK for production build
i have to add "packageType": "apk" in my build.json.
and use:
ionic cordova build android --configuration production --release --buildConfig=build.json

or
just call
ionic cordova build android --configuration production --release -- -- --packageType=apk

Am i right?

[erisu]

I do not know the Ionic CLI is structured, how it pipes values to Cordova CLI, or how it is used.

But with Cordova CLI, the command is:

cordova build android --release -- --packageType=apk

I don't know what --configuration production is.

The build config should work as long as the correct property is defined.

For this PR description which mentioned--buildType=apk, that was a mistake. I meant to say packageType.

Thank you for the clarification.
