uncaught exception - Canvas texture format `rgba16float` is not yet supported

[dkorpel]

When opening https://webgpu.github.io/webgpu-samples/?sample=particles on FireFox 150.0.2 (64-bit), Windows 11:

uncaught exception, please report a bug!
  https://github.com/webgpu/webgpu-samples/issues/new
TypeError: GPUCanvasContext.configure: Canvas texture format `rgba16float` is not yet supported. Subscribe to <https://bugzilla.mozilla.org/show_bug.cgi?id=1834395> for updates on its development in Firefox.

While the implementation is up to FireFox, the expected behavior for the webgpu sample is to catch and report the Exception gracefully instead of saying "uncaught exception, please report a bug!".
