ggcr:Bad request when patching a layer to distribution/registry

[warrenhodg]

Describe the bug

When using go-containerregistry to upload helm charts to an OCI registry (distribution/registry), using the vSphere networking, I receive a 400 Bad Request response.

Workarounds that mitigate the problem are:

• Replacing the compressed layer streaming logic with ioutil.ReadAll into a []byte and performing the HTTP Patch request using that as the body instead
• Using a local port-forward logic such as sudo ncat --sh-exec "ncat 10.220.54.215 30000" -l 30000 --keep-open

To Reproduce

Using a vSphere network connected to a Kubernetes NodePort exposed service for a pod running distribution/registry running in Kubernetes, and using the library to push a helm chart to the registry.

Expected behavior

The helm chart is uploaded.

• I am using v0.20.1 of the go-containerregistry library
