Description of problem:
When creating a virtual machine and adding network information using cloud-init, the YAML code for this VirtualMachine generated by the console is not correct.

How reproducible:
100%

Steps to Reproduce:
1: From the console, create a RHEL9 VM using the template, customize virtual machine
2: Add a secondary Network interface
3: Go to scripts => Edit cloudinit => "Add network data" => use
Ethernet name: eth1
IP addresses: 10.10.21.32/24

(though the instructions say "Use commas to separate between IP addresses", this would generate an error in ifcfg-eth1 on the virtual machine, which resulted in an error by the NetworkManager)

Actual results:
Go to "YAML", the generated code is:
networkData: |
network:
version: '1'
config:

• type: physical
  name: eth1
  subnets:
• type: static
  address:
• 10.10.21.32/24
  gateway: 10.10.21.1

Expected results:
networkData: |
network:
version: 1
config:

• type: physical
  name: eth1
  subnets:
• type: static
  address: 10.10.21.32/24
  gateway: 10.10.21.1

This means there are 2 errors:
1) '1' should be replaced by 1
2) address should not be a list of items
