Description of problem:

When I am creating an Hostgroup, I can select the Domain but the associated subnets are not showing selectable in the "IPv4 Subnet" field.

Version-Release number of selected component (if applicable):

satellite-6.14.0-3.el8sat.noarch
foreman-3.7.0.2-1.el8sat.noarch
katello-4.9.0-1.el8sat.noarch

How reproducible:

100%

Steps to Reproduce:
1. Build a Satellite 6.14.0
2. Create a domain
3. Create a ipv4 subnet and associate the domain with the subnet
4. From WebUI, Try creating a hostgroup and select the "Domain" in Networks tab.

Actual results:

Domain is selected but "IPv4 Subnet" field keeps on showing "No Subnets".

( screenshots attached to showcase the issue )

Expected results:

Subnets should be listed for selection if they are properly associated with the Domain
