[DOC OCP] Customer feedback - AMQ Streams container images are not documented

In section 2.1, Installing AMQ Streams and deploying components, we have a link to the Red Hat Container Catalog. However, we do not provide a list of all the Streams container images. A customer has requested that we provide documentation on each image so they can customise their installation. The suggestion is to add a list of all the images to the same section.
