Fail CLI early if the release image is not multi-arch and the management cluster's CPU architecture is not the same as the NodePool's CPU architecture

User Story:

As a user of the HyperShift CLI, I would like the CLI to fail early if these conditions are all true:

• the release image is not multi-arch
• the management cluster's CPU architecture is not the same as the NodePool's CPU architecture

so that we can prevent a HostedCluster from being created that will have errors due mismatches between the release image, management cluster's CPU architecture, and NodePool's CPU architecture.

Acceptance Criteria:

• The HyperShift CLI fails to create a cluster when the release image is not multi-arch and the management cluster's CPU architecture does not match the NodePool's CPU architecture.
• There is documentation providing information the CLI will fail when it meets the conditions above.

(optional) Out of Scope:

This should be done for the API as well but will be covered thru HOSTEDCP-1105.

Engineering Details:

• HyperShift CLI currently defaults to a multi-arch image in version.go.
