Gradle Module Metadata not published

The latest versions of the library claim to have been published with GMM (Gradle Module Metadata) as per the `pom` file:
```xml

4.0.0
com.google.android.apps.common.testing.accessibility.framework
accessibility-test-framework
4.1.1
aar
Accessibility Test Framework
```
However, the GMM `.module` artifact is not actually available on the [Google Maven repo](https://maven.google.com/web/index.html?q=acces#com.google.android.apps.common.testing.accessibility.framework:accessibility-test-framework:4.1.1). Only the pom, aar, javadoc are published. This can cause issues when importing this dependency to an internal repository instance.
