Title:
Use less generic name for monitors.xml to avoid clashing with other
desktops

Bug description:
#### Expected behaviour
cinnamon is using a dedicated name, cinnamon-monitors.xml. This doesn't cause
the file to be overwritten by the display preferences if other desktop
environment are used on the same distro. If MATE and GNOME followed the same
approach, the file name would be mate-monitors.xml, and gnome-monitors.xml,
respectively.
#### Actual behaviour
GNOME's monitors.xml:
```
<monitors version="2">
<configuration>
<migrated/>
<logicalmonitor>
<x>0</x>
<y>0</y>
<primary>yes</primary>
<monitor>
<monitorspec>
<connector>Virtual-1</connector>
<vendor>???</vendor>
<product>0x0000</product>
<serial>0x00000000</serial>
</monitorspec>
<mode>
<width>1600</width>
<height>900</height>
<rate>60</rate>
</mode>
</monitor>
</logicalmonitor>
</configuration>
<configuration>
<logicalmonitor>
<x>0</x>
<y>0</y>
<scale>1</scale>
<primary>yes</primary>
<monitor>
<monitorspec>
<connector>Virtual-1</connector>
<vendor>unknown</vendor>
<product>unknown</product>
<serial>unknown</serial>
</monitorspec>
<mode>
<width>1600</width>
<height>900</height>
<rate>60</rate>
</mode>
</monitor>
</logicalmonitor>
</configuration>
</monitors>
```
MATE's monitors.xml:
```
<monitors version="1">
<configuration>
<clone>no</clone>
<output name="Virtual-1">
<vendor>???</vendor>
<product>0x0000</product>
<serial>0x00000000</serial>
<width>1600</width>
<height>900</height>
<rate>60</rate>
<x>0</x>
<y>0</y>
<rotation>normal</rotation>
<reflect_x>no</reflect_x>
<reflect_y>no</reflect_y>
<primary>yes</primary>
</output>
<output name="Virtual-2">
</output>
<output name="Virtual-3">
</output>
<output name="Virtual-4">
</output>
</configuration>
</monitors>
```
#### Steps to reproduce the behaviour
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`
Steps I used to reproduce the issue in Ubuntu 22.04 (as a virtual machine):
* Log into GNOME
* Ubuntu comes with GNOME, so install MATE in addition: `sudo apt-get install
mate-desktop-environment-extras mate-desktop-environment`
* Run `$ gnome-control-center display`, change the "Resolution" to 1600x900,
click on the "Apply": This will 1) generate "$HOME/.config/monitors.xml", 2)

Close the window.
* Log out from GNOME. From the display manager, log into MATE.
* As you can see, the [screen resolution (1600x900 configured in GNOME) not
used by
MATE](https://github.com/mate-desktop/mate-control-center/assets/6416073/adffa08e-cf08-499d-8dc3-9e7800e4d7e9),
instead a fallback resolution is used.
* Run `$ mate-display-properties`, just click on the "Apply" button (you
don't have to click on the "Keep this configuration" button that pop-ups in the
dialoge-box), it will overwrite "$HOME/.config/monitors.xml"
* Log out from MATE. From the display manager, log into GNOME.
* As you can see,
