Update compileSdkVersion and GAM

Describe the bug Internal test app is not built after the automatic updating of GAM.

[ ] compileSdkVersion and targetSdkVersion must be updated to the latest version (34) for the SDK and for all of the apps.
[ ] GMA version must be updated in maven publishing scripts GAM and AdMob integration scenarios.
[ ] After that run autotests to check that the SDK works great.

2 issues were found when checking AAR metadata:

  1.  Dependency 'androidx.privacysandbox.ads:ads-adservices-java:1.0.0-beta05' requires libraries and applications that
      depend on it to compile against version 33 or later of the
      Android APIs.

      :PrebidInternalTestApp is currently compiled against android-32.

      Recommended action: Update this project to use a newer compileSdkVersion
      of at least 33, for example 33.

      Note that updating a library or application's compileSdkVersion (which
      allows newer APIs to be used) can be done separately from updating
      targetSdkVersion (which opts the app in to new runtime behavior) and
      minSdkVersion (which determines which devices the app can be installed
      on).
