GNOME: add support for version 44

[matttbe]

First, thank you for maintaining this very useful add-on!

When using GNOME 44 beta (44~beta-1ubuntu1 on Ubuntu 23.04), I got this warning after having forced version 44 support in metadata.js:

JS ERROR: TypeError: Meta.later_add is not a function
vfunc_allocate@${HOME}/.local/share/gnome-shell/extensions/wsmatrix@martin.zurowietz.de/overview/thumbnailsBox.js:187:26
vfunc_allocate@resource:///org/gnome/shell/ui/overviewControls.js:195:40

_makeEaseCallback/<@resource:///org/gnome/shell/ui/environment.js:151:22
_easeActorProperty/<@resource:///org/gnome/shell/ui/environment.js:317:60

I simply applied the same fix as this one: https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/8d68bdaaa163

I guess this modification breaks the compatibility with older versions but I didn't investigate more.

Apart from that, the rest seems working fine, tested on Wayland only.

Thanks! This works here.

Thanks, I'll test this once GNOME 44 is available in my Arch VM.

works great under ubuntu 23.04/x11

Alright. While I couldn't test it myself so far, I'll trust your reports and merge.

This worked for me as well on 23.04 with wayland. Thank you!
