When attempting to assign a release version to multiple content hosts through bulk selection in the Satellite WebUI, the operation fails or is unavailable. This prevents administrators from efficiently managing host configurations at scale.

Steps to Reproduce:

1. Navigate to:
   Satellite WebUI → Hosts →{{ Content Hosts}}

1. Select multiple content hosts from the list.

1. Click on Select Actions → Assign Release Version

1. Release versions keep on loading.

Expected Behavior:
The system should allow assigning a release version to multiple selected content hosts in one action.

Impact:
This limitation forces admins to assign the release version to one host at a time by clicking on individual hosts, leading to inefficiency and a higher risk of misconfiguration in large-scale environments.
