NoCloud - network_config bridges with set-name not configured by NM renderer

[xiachen-rh]

Bug report

Creating two bridges on top of two interfaces using Network-Config version 2 for cloud-init, using NetworkManager renderer, cloud-init failed stage init-local with KeyError.
https://issues.redhat.com/browse/RHEL-52718

Environment details

• Cloud-init version: cloud-init-23.4
• Operating System Distribution: rhel 9.4
• Cloud provider, platform or installer type: KVM, NoCloud

How reproducible:
100%

##Steps to reproduce the problem
I used the same Network-Config data with #5574 but using NM renderer.
modified /etc/cloud/cloud.cfg to
  network:
    renderers: ['network-manager', 'eni', 'netplan', 'sysconfig', 'networkd']

network-config

 network:
  bridges:
    baremetal:
      addresses:
      - fc00:1:1::2/64
      interfaces:
      - baremetalport
      nameservers:
        addresses:
        - fc00:1:1::1
      routes:
      - on-link: true
        to: ::/0
        via: fc00:1:1::1
      stp: false
    provisioning:
      addresses:
      - fc00:1:2::2/64
      interfaces:
      - provisioningport
      routes: []
      stp: false
  ethernets:
    baremetalport:
      match:
        macaddress: 52:54:00:bd:8f:cb
      set-name: baremetal0
    provisioningport:
      match:
        macaddress: 52:54:00:25:ae:12
      set-name: provisioning0
  renderer: NetworkManager
  version: 2

Command used to build config-drive ISO image:
genisoimage -output config-drive.iso -volid CIDATA -joliet
-rock user-data meta-data
network-config

Create a VM in libvirt with two network interfaces, match MAC address of network-config.
Boot the VM

Expected results
The VM should boot and correctly configure the network interfaces and bridges.

Actual results
cloud-init failed stage init-local with KeyError.
