Ruff activation on Dev Container Environments

[Marc Ramirez Invernon]

Setup information

• Remote Development extension pack
• Macbook M1
• Ruff 0.2.0 vscode extension

.devcontainer.json config

{
    "image": "python:3.11.8",
    "name": "python-environment",
    "runArgs": ["--name=python-dev-environment", "--rm"],
    "features": {
        "ghcr.io/devcontainers/features/common-utils:2": {}
    },
    "customizations": {
        "vscode": {
            "extensions": [
                "ms-python.python", 
                "ms-toolsai.jupyter", 
                "equinusocio.vsc-material-theme-icons", 
                "charliermarsh.ruff"
            ]
        }
    },
}

My guess is Ruff doesn't detect Python extension on the first build. The user need to restart the window to make Ruff aware of Python extension installed on the container.

Do you see the same behavior if you use one of the Microsoft-published extensions, like Black or isort? If so, this may be an issue for Microsoft's extension template.

I try it and back to you if the issue is different.
