feat(initramfs): accept other media types

We used to only accept the old ManifestV1 response type. However, most
images don't come with this manifest type anymore, but instead has a
ManifestV2 List / OCI Spec'd manifest.

This commit handles those manifests types:
- OCI List
- ManifestV2 List
- ManifestV2
