Community plugins fail to install in Red Hat Developer Hub 1.9+ due to network restrictions in disconnected environments.

Issue

• After upgrading to Red Hat Developer Hub (RHDH) 1.9 or later, pods fail to start or initialize, and are unable to install certain community-supported dynamic plugins.
• The install-dynamic-plugins init container logs show network timeout or connection errors when attempting to download plugin artifacts:

Error: Failed to fetch package metadata from ghcr.io dial tcp: i/o timeout

• In restricted, disconnected, or air-gapped environments, network firewalls or proxies must allow traffic to the specific external registries hosting these dynamic plugins.
