[Feature request] mate-display-properties: Please upgrade monitors.xml from <monitors version="1"> to <monitors version="2">

Both GNOME and MATE can be installed on the same distro. Both DEs are installing "$HOME/.config/monitors.xml" via manually configured display GUI preferences:
* GNOME via `$ gnome-control-center display`
* MATE via `$ mate-display-properties`

GNOME's monitors.xml is starting with <monitors version="2">, and that MATE's monitors.xml is starting with <monitors version="1">. They are incompatible, see https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2028469 -- but even if MATE is starting to use version 2, there will certainly come times when both GNOME and MATE is not able to use the same version of monitors.xml in the future. However, it would still be useful to upgrade monitors.xml for MATE in order to use a more modern scheme.

########
Ubuntu MATE 22.04, and 23.04 is monitors.xml with <monitors version="1"> that is looking like this:

```
<monitors version="1">
  <configuration>
      <clone>no</clone>
      <output name="Virtual-1">
          <vendor>???</vendor>
          <product>0x0000</product>

          <width>1600</width>
