What would you like to be added:
It should be possible to upload resources to a "maven" repository after transport. The uploader should use configuration from the credential provider in the OCM library to get the credentials. In addition to that configuration that contains the target maven repository is also required. Therefore a new uploader (https://github.com/open-component-model/ocm-spec/blob/main/doc/02-processing/04-digest.md?plain=1#L649) for this type is required.

Why is this needed:
To be able to mimic the same repository setup on target side that is available on source side, the OCM tooling needs to provide uploaders for all existing technologies, here "maven".
