Local feature not working in Remote-Containers

[chrmarti]

Remote-Containers 0.244.0

Using:

{
	"context": ".",
	"dockerFile": "Dockerfile",
	"features": {
		"./local-features/foo": "latest"
	}
}

fails with:

ENOENT: no such file or directory, lstat '/Users/chrmarti/.vscode-insiders/extensions/ms-vscode-remote.remote-containers-0.244.0/local-features/foo'

On Windows, I get the error "Expected feature identifier to contain only alphanumeric and/or the '-' characters."
I'm also unable to build the container with that configuration.

Thanks @rzhao271, the following verifies the fix:

File layout:

devcontainer.json:

{
	"image": "ubuntu:latest",
	"features": {
		"./foo": "latest"
	}
}

devcontainer-feature.json:

{
    "id": "foo"
}

install.sh:

#!/bin/sh

echo HERE!
echo THERE! >/there.txt

In the devcontainer check that the file /there.txt exists.

(If you want to reproduce the problem in 0.244.0 first, you need to change the feature's path in the devcontainer.json to "./.devcontainer/foo". This changed later to be relative to the devcontainer.json.)
