Breaking change:
Deprecation of podman + ImageStreams Approach, requiring users to transition to oc-mirror for Helm chart mirroring.

Support for oc-mirror Helm Chart Mirroring. Users can now mirror Helm charts and related container images using oc-mirror partially disconnected and fully disconnected environments, ensuring a Red Hat-supported airgapping process.

The current developer hub air-gapped installation documentation here:

https://access.redhat.com/documentation/en-us/red_hat_developer_hub/1.0/html/administration_guide_for_red_hat_developer_hub/con-airgapped-environment_admin-rhdh

uses Podman to pull several container images and then push them to the openshift cluster internal registry. There are several things that need to be updated:

Podman push/pull from the same host is not how most air-gapped systems function. Most require that an archive be created on host A while connected to the internet, moved into the air-gapped environment on host B, and then pushed into a registry.
RHDH is installed with a helm chart. The Red Hat supported method for mirroring helm charts for air-gapped installations is to use oc-mirror which handles the first point.
The air-gapped documentation does not describe how to obtain the helm chart needed to install RHDH offline. The documentation simply points to another doc that describes a general helm chart based RHDH installation using the OpenShift console.
