Update Red Hat Catalog page for official Couchbase Server container

Couchbase is responsible for keeping content up to date on several pages in the Red Hat Ecosystem Catalog. One of these pages is for the official RHEL-based Couchbase Server container: https://catalog.redhat.com/software/containers/couchbase/server/59f051fa2937384ff320d995

The content for the equivalent page in Docker Hub for the official Ubuntu-based Couchbase Server container is being evaluated and updated per MB-38022 and MB-41714. Therefore, this ticket is being raised to suggest that the page in the Red Hat Ecosystem Catalog is also evaluated to ensure that it is up to date and consistent with the changes that have been made to the Docker Hub page.

It's important that the Red Hat and Docker pages stay consistent and relevant. Any update to one of these pages should be evaluated and applied to the other where applicable.
