Description of problem:
When trying to sync one particular image from quay.io in Satellite, I get a warning that in-toto mediaType is not supported, preventing me from syncing that image.

Version-Release number of selected component (if applicable):
6.13.0 snap 13

How reproducible:
always

Steps to Reproduce:
1. Create a docker-type repo:
url: https://quay.io
name: satelliteqe/robottelo
2. Try to sync it.

Actual results:
Katello::Errors::Pulp3Error

{'errors': [{'code': ErrorDetail(string='MANIFEST_INVALID', code='parse_error'), 'message': ErrorDetail(string="layers.0.mediaType: 'application/vnd.in-toto+json' is not one of ['application/vnd.oci.image.layer.v1.tar', 'application/vnd.oci.image.layer.v1.tar+gzip', 'application/vnd.oci.image.layer.v1.tar+zstd', 'application/vnd.oci.image.layer.nondistributable.v1.tar', 'application/vnd.oci.image.layer.nondistributable.v1.tar+gzip', 'application/vnd.oci.image.layer.nondistributable.v1.tar+zstd']", code='parse_error'), 'detail': {'digest': ErrorDetail(string='sha256:88c309cdeefa131e80756239508286fd26fc9f993b85dd2037fb83803e11c727', code='parse_error')}}]}

I'd like to have that mediaType support added.
