Update CLI args for --web-renderer to explain new default and clarify "skwasm" #151786
Description
- Skwasm is not experimental (any longer)
- It's the only renderer used when compiled to wasm
We should explain this!
--web-renderer The renderer implementation to use when building for the web.
[auto] Use the HTML renderer on mobile devices, and CanvasKit on desktop devices.
[canvaskit] Always use the CanvasKit renderer. This renderer uses WebGL and WebAssembly to render graphics.
[html] Always use the HTML renderer. This renderer uses a combination of HTML, CSS, SVG, 2D Canvas, and WebGL.
[skwasm] Always use the experimental skwasm renderer.
