Gradle 8.6 reports deprecation warnings with plugin version 5.2.0

[bmeier-pros]

Describe the bug

After upgrading to plugin version 5.2.0, we started receiving deprecation warnings from Gradle 8.6 that were not present with version 5.1.14. After downgrading back to 5.1.14, the deprecation warnings went away.

            repoKey = isRelease ? releaseKey : snapshotKey
            username = artifactory_user
            password = artifactory_password
        }
        defaults {
            publications ('ALL_PUBLICATIONS')
