added export instruction for auth package

[pulguptaAdobe]

Description

Recently we upgraded to 1.1.12 version of the sdk and started using com.adobe.aio.auth but we were not able to start our bundle on AEM since the artifact aio-lib-osgi is not exporting this package. Added this package in the export list so that the dependent bundles can access the classes of this package.
