Remove Gradle .module files from Maven package validation (#1370)

validatePackageContents.ps1 expected .module and .module.asc files,
which are Gradle Module Metadata artifacts. The pipeline publishes with
Maven (./mvnw), which does not generate .module files, causing the
validation step to fail. Remove the two Gradle-only entries from the
expected files list.
