Get devcontainer indexed in VS Code community containers

[nuvious]

VS Code has a dev container wizard to Add Dev Containers Configuration File which offers a list of microsoft maintained dev containers but also adds the option to Show All Definitions.... This displays a list of community maintained containers:

The full list of these containers is maintained here and to get into this list one only needs to submit a pull request to this yaml file definition.

The entries for dev container templates take the following format:

- name: Templates by John Muchovej
  maintainer: John Muchovej
  contact: https://github.com/jmuchovej/devcontainers/issues
  repository: https://github.com/jmuchovej/devcontainers
  ociReference: ghcr.io/jmuchovej/templates

They also seem to use the devcontainer github action to publish releases that then get picked up by the VS Code community devcontainer scraper. Project structure template is available here.

Will probably get to this in my 'spinning wheels time' waiting for builds so submitting this for documentation/tracking as well as just brain-dumping what I learned about indexing the devcontainer in VS Code.
