multiwebview example doesn't support wayland

[happybeing]

Describe the bug

cargo run example multiwebview
...
thread 'main' panicked at examples/multiwebview.rs:26:7:
This example doesn't support wayland!

Same for examples wgpu and winit. I guess this is expected but as multiwebview was the first example I tried I opened an issue. I suggest the solution is to describe any limitations for the examples in the README so new arrivals can avoid thinking that wry is broken when first trying it out.

Steps To Reproduce
See above.

Expected behavior
No panics!

Platform and Versions (please complete the following information):
OS: Ubuntu 22.04.04 LTS
cargo 1.74.1 (ecb9851af 2023-10-18)
rustc 1.74.1 (a28077b28 2023-12-04)

bump.
being able to render a webview within wgpu would be a godsend for the current project I'm working on.
I need the ability to pass a raw pixelbuffer of the window from one wayland surface to another.
