Title:
  dns search domain gets duplicated

Status in subiquity:
  New
Status in subiquity package in Ubuntu:
  Confirmed

Bug description:
  When configuring the network on Ubuntu Server 22.04.1 Installer with Subiquity 22.10.1 entering the same search domain in both IPv4 and IPv6 makes it appear twice in the generated netplan config.
  Editing the search domain in either IPv4 or IPv6 seems to duplicate them even further.

  e.g.:
  network:
    ethernets:
      enp1s0:
        addresses:
        - [IPv4]/24
        - [IPv6]/64
        nameservers:
          addresses:
          - [IPv4]
          - [IPv4]
          - [IPv6]
          - [IPv6]
          search:
          - example.com
          - example.com
        routes:
        - to: default
         via: [IPv6]
    version: 2

  For that the default route gets only generated once see Bug #1993792.
