[ci] Use long version for maestro publishing (#8964)

Commit bbac9fe ran into some issues when attempting to publish to maestro:

    error : Asset 'D:\a\_work\1\a\7dc04dfe-406a-4fa3-aea0-199acc2763fa\MergedManifest.xml' already exists with different contents at assets/manifests/xamarin-xamarin-android/34.99.0-dev/MergedManifest.xml

We should be able to fix this by using the long package version which
optionally includes pre-release labeling and commit distance info.
