Change default start scripts from X11 to Wayland (#4011)

This PR changes the default `start` and `start:dev` scripts to use
Wayland instead of X11. I think after three years, it's time to take
this step.

### Background

Since Raspberry Pi OS Bookworm (2023), Wayland is the default display
server. As most MagicMirror installations run on Raspberry Pi, this
change aligns with what new users already have installed.

### Benefits

Especially for new users (which install the OS with Wayland) it's easier
- they can simply run `npm start` without needing to understand display
server differences or manually switch scripts.

And for projects in general it's better to rely on modern defaults than
on legacy.

### Breaking Changes

**None** - X11 support is maintained. Users who really use and need X11
can use `node --run start:x11`.
