Custom devcontainer features and images.
Bump version in features/src/<name>/devcontainer-feature.json, then create a GitHub Release tagged features/<name>/vX.Y.Z with the same version. It publishes the feature to ghcr.io/shokkunrf/devcontainer-features/<name>.
Create a GitHub Release tagged images/<name>/vX.Y.Z. It builds the image for amd64 and arm64 and pushes it to ghcr.io/shokkunrf/devcontainer-images/<name> with the X.Y.Z, X.Y, X, and latest tags. A prerelease pushes only the sha-<commit> tag.
