Add github action to trigger metamask-desktop CI (#17977)

* chore: add action to trigger metamask-desktop ci

We want to be able to trigger
MetaMask Desktop CI whenever we
are releasing the Extension (in this
case, merging to master branch).
This will allow the desktop team
to easily identify whenever a breaking
change (to the extension-desktop app
pairing) is being released and address
the issue within the desktop app
in a timely manner

* use double quotes

ensure these get interpreted as single strings.
