CI: move to github container registry (#7652) #169

	name: "Build devcontainer"

	# Since building of containers can be quite time consuming, and take up some storage,
	# there is no need to finish a build for a tag if new changes are concurrently being made.
	# This cancels any previous builds for the same tag, and only the latest one will be kept.

	group: ${{ github.workflow }}-${{ github.ref }}
	cancel-in-progress: true
