pulling the OSOK container gives unauthorised error

[atimgraves]

The instructions say to install the OSOK, however attempting to pull the bundle results in an Unauthorised error
docker pull iad.ocir.io/oracle/oci-service-operator-bundle:1.1.1
The same applies when trying to use the operator-sdk to install it.
The container image repo needs to be made public readable
(This also applies to the 1.1.0 version, I haven't tested others, but I suspect as they are tags on the same repo that this will apply to all versions)
