Upgrade build code for Gradle 8 to remove deprecated uses

Fixes build errors that appeared as warnings in Gradle 7:

* Configurations no longer allowed as Dependencies

* AbstractArchiveTask API Cleanup: Deprecated properties `baseName`, `extension`, `destinationDir`, and `version` have been removed in Gradle 8. Instead use `archiveBaseName`, `archiveExtension`, `destinationDirectory`, and `archiveVersion`.
