Build fails because .aab files cannot be deployed using Central Portal

[wborn]

After merging #35 it seems that the Central Portal currently does not support publishing .aab files (https://developer.android.com/guide/app-bundle).

 FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':GenericApp:app:publishReleasePublicationToSonatypeRepository'.
> Failed to publish publication 'release' to repository 'sonatype'
   > Could not PUT 'https://central.sonatype.com/repository/maven-snapshots/io/openremote/app/1.4.0-SNAPSHOT/app-1.4.0-20250516.125650-1.aab'. Received status code 400 from server: Detected content type [application/zip, application/x-zip-compressed], but expected [application/x-authorware-bin]: /io/openremote/app/1.4.0-SNAPSHOT/app-1.4.0-20250516.125650-1.aab

I've mailed Central Support to figure out if this is due to a server configuration issue or whether this content is no longer supported.

Sonatype mailed me they reconfigured their servers to be more permissive. This has fixed the snapshot build.
