python feature not compatible with alpine - better error message

This is my devcontainer.json:

{
	"name": "Alpine",
	"image": "mcr.microsoft.com/devcontainers/base:alpine-3.17",
	"features": {
		"jupyterlab": "latest"
	}
}

Opening the dev container produces the following error:

The error #0 0.462 ./install.sh: line 190: apt-get: command not found sounds like the user did something wrong.

It would be much more helpful to get a clear error message saying that the python feature does not support the alpine distro.

Hi 👋

Every Feature currently has a OS support section in the README. However, I agree we should add clear messages in the Feature itself 💡 Thanks!

Then I suggest to make the OS support section machine readable and offer a linting rule in the devcontainer json in VS Code.
