Wayland support

[qu35t-code]

Description

Hey @Dramelac,

Here's an addition to set the correct environment variables for wayland. I started with this observation:

docker run -it -e XDG_RUNTIME_DIR=/tmp -e WAYLAND_DISPLAY=$WAYLAND_DISPLAY -v $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY:/tmp/$WAYLAND_DISPLAY debian bash

➜  ~ echo $WAYLAND_DISPLAY
wayland-1

[*] Location of the exegol workspace on the host : /home/qu35t/.exegol/workspaces/htb

[-] The xhost command is not available on your host. Exegol was unable to allow your container to access your graphical environment (or you don't have one).

Authorization required, but no authorization protocol specified

Error: cannot open display: :0

I've modified the code to add a check on the display server and return the correct environment variables if this is the case.
There's one step missing (and I'm struggling):

You need to add a volume:

-v $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY:/tmp/$WAYLAND_DISPLAY

With my modifications, the following command works: (the xhost warning must also be removed)

(venv) ➜  Exegol git:(wayland) python3 exegol.py start -V $XDG_RUNTIME_DIR/$WAYLAND_DISPLAY:/tmp/$WAYLAND_DISPLAY wayland2

The PR is incomplete, but it's already a very good start, and I'm taking over the rest internally on the repo.
Thank you very much!
