#225 introduced a new page for wasm examples at https://bevyengine.org/examples/

This page is currently lacking in style and not linked from the website. I think it should be the main page for example discovery instead of the git repo:

• it is easier to ensure that the examples are at the latest tag instead of main as the website is only about latest
• it is easier to evolve organisation with tags and categories instead of just a list of folders
• it is easier to control presentation as GitHub will always show files first, then the optional readme.md
• it is easier to have a nice presentation instead of just one large and basic readme.md

So... in case it's not clear, I think it would be easier.

What would be needed to get it in top shape:

• add medatada to Cargo.toml about each example [Merged by Bors] - Examples metadata in Cargo.toml bevy#4741
  • display name
  • description
  • wasm enabled
• add an example page built with the dev docs
• update the website to display all examples with their metadata, but only build wasm version for the one where it is enabled
  • WebGPU: Webgpu example pages #630
  • WebGL2: Examples update #720
  • non Wasm compatible: Show WASM-incompatible examples #1024
• remove/simplify the readme.md in bevy repo example folder. This file can't scale
• link more prominently to the website for examples [Merged by Bors] - Make web examples more visible #335
• (optional) add screenshot of the examples as part of the metadata Webgpu example pages #630
• (optional) add tags to the metadata to help with discovery Add Search on Examples page #742

This should be tied with #159 (bevy assets page) to evolve a consistent style.

The first two points need to be done before a release, the two next with that release
