${devcontainerId} is not added to the file

Testing #7405

Use following devcontainer.json:

{
	"image": "mcr.microsoft.com/devcontainers/base:0-focal",
	"features": {
		"./test-feature": "latest"
	},
	"postCreateCommand": "echo ${devcontainerId} >~/devcontainerId.txt",
	"containerEnv": {
		"CONTAINER_ENV_DEVCONTAINER_ID": "${devcontainerId}"
	},
	"remoteEnv": {
		"REMOTE_ENV_DEVCONTAINER_ID": "${devcontainerId}"
	}
}

${devcontainerId} variable is not replaced and copied into the devcontainerId.txt file in the postCreateCommand

Christof Marti (@chrmarti) May I know if the fix is available in latest release so that I can verify?
