As a result of the rebranding of the Red Hat OpenShift Data Science product to be Red Hat OpenShift AI, the user documentation for OAI 2.5 onwards must be rebranded to remove occurrences of the old product name, and to introduce occurrences of the new product name.

For information on the high-level tasks required, please refer to the Jira stories in this epic, and also the spike linked below.
