Create the process necessary that exports examples in `bevy_examples` to the website.

To ensure the `bevy_examples` crate is ok to use for example export to the website, set up the relevant job and ensure that the example (`2d_shapes`, should be the only one in `bevy_examples` for now) is updated on the website. If needed to verify, maybe add some non intrusive flavor text to the example so that one can easily tell the visual difference that the example in bevy_examples has successfully been put onto the website.

Start by reading the bevy_examples crate, especially the 2d_shapes example, and locate the repository's website-export job or workflow entry point. Trace how that example is selected and published, then verify that 2d_shapes is updated on the website; any added flavor text should make the successful export visually identifiable.
