Fix assert on unknown packageType when ralfpack is not used

[astolcenburg]

Ref: #RDKEAPPRT-936

[Copilot]

Pull request overview

This PR removes a strict assertion around packageType when generating the OCI artifact manifest in the non-ralfpack packaging path, preventing failures for unknown (or newly introduced) package types while keeping the manifest/layer format consistent with the current EROFS+dm-verity packaging flow.

Changes:

• Stop passing config.packageType into makeArtifactManifest() and remove the layer mediaType override in pack.cjs.
• Simplify makeArtifactManifest() by removing the packageType→filename mapping and the corresponding assert, and make the layer mediaType consistently erofs+dmverity.
