List on containers.dev

[evilhamsterman]

This may have been originally written for Codespaces, but Codespaces are basically just fancy devcontainers and this works just fine in a regular devcontainer like in VSCode. If you list this on containers.dev it will be easily discoverable to anyone using devcontainers. You can do so by creating a PR for this file https://github.com/devcontainers/devcontainers.github.io/blob/gh-pages/_data/collection-index.yml
