new WebGPU support for Safari on macOS 26, iOS 26, iPadOS 26, and visionOS 26

[realhackcraft]

How can Bevy's documentation be improved?

On the WebGPU examples, there is a support warning banner. It doesn't state the availability of WebGPU on this year's apple OSes, which come with WebGPU enabled by default.

I understand that these are still in developer beta, but it's still good to list them in the warning.

Example warning:

I would prefer to wait for macOS 26 to be released, and then relax the text to mention checking for browser compatibility if nothing is displayed without specifying any browser / version

Or maybe catch the error when trying to create a webgpu context and display something in js
