Plain `.devcontainer.json` contains empty `build` key

[luebken]

What happened? For a simple Javascript project like https://github.com/luebken/hello-nodejs the built-in language detection creates the following .devcontainer.json:

{"image":"mcr.microsoft.com/devcontainers/javascript-node","build":{}}

When opening the code the following warning is shown VSCode:

Property build is not allowed.

What did you expect to happen instead? I expect .devcontainer.json to only contain the image key, so no warning is shown.

How can we reproduce the bug? (as minimally and precisely as possible)

• clone https://github.com/luebken/hello-nodejs
• devpod up .
• open vscode > View > Problems

Local Environment:

• DevPod Version: v0.1.9
• Operating System: mac
• ARCH of the OS: ARM64

DevPod Provider:

• Local/remote provider: docker

Anything else we need to know? From my understanding, the issue here is how Go marshals nested structs, which is how the ConfigBuildOptions are defined: https://github.com/loft-sh/devpod/blob/main/pkg/devcontainer/config/config.go#L215

@luebken thanks for creating this issue! You are correct, we should fix this, thanks for the analysis.
