Gradle 9: new RootComponentIdentifier type

[Technici4n]

Gradle 9.0.0 introduces RootComponentIdentifier), a new subtype of ComponentIdentifier).

APIs which return instances of ComponentIdentifier may now return identifier instances of this new type. For example, the ComponentResult), ResolvedVariantResult), and ArtifactView) APIs, among others, are affected.

See: https://docs.gradle.org/9.0.0-rc-3/userguide/upgrading_major_version_9.html#new_subtypes_of_componentidentifier_introduced

We have to check if this will cause issues in MDG, since we do perform instanceof checks for ComponentIdentifier subclasses.
