We’ve noticed that some users still include the URL scheme and full path
when logging into an OCI registry, for example:
```sh
helm registry login -u $OCI_REGISTRY_USER --password-stdin oci://ghcr.io/org/repo
```
This is no longer necessary and will not be supported in Helm v4.
To guide users toward the correct usage, we should show an example of
the ideal command.

In Helm v3 we did not change exit codes for existing commands to
maintain compat. A flag was introduced so a failure would result
in a non-0 exit code. A note was left to make this the default
in Helm v4. That's what this change does.
