The current RHDH documentation for air-gapped installation using Helm Charts is outdated and incompatible with oc-mirror v2. We need this update to reflect the new API versions, command syntax, and workflow changes introduced in oc-mirror v2.

Affected doc: https://docs.redhat.com/en/documentation/red_hat_developer_hub/1.5/html-single/installing_red_hat_developer_hub_in_an_air-gapped_environment/index#proc-install-rhdh-helm-airgapped-full.adoc_title-install-rhdh-air-grapped

Sections requiring updates:

• Chapter 3.1: Installing Red Hat Developer Hub on OpenShift Container Platform in a fully disconnected environment with the Helm chart
• Chapter 3.2: Installing Red Hat Developer Hub on OpenShift Container Platform in a partially disconnected environment with the Helm chart
