gnome-shell-extension-multi-monitors crashes on LTS 20.04

gnome-shell-extension-multi-monitors crashes because it's out of date and the new version on github isn't in the package manager

The code crashing it has been removed in this commit https://github.com/spin83/multi-monitors-add-on/commit/15a0d3ceea6a601d4c4b709a0fd655ff7d6d27ea#diff-a90eb6aeed84b64a03b86f59cbf3d134dd1037ed6f29bdb6eb389530f32dd435

but the version from the package manager is stale and doesn't work anymore on LTS20.04
