add e2e envs to devcontainer

[ykadowak]

Description:

This PR adds E2E environment to our VS Code devcontainer. With this devcontainer environment, we can just start k8s cluster with k3d, deploy vald, and run e2e without any additional operation.

Made the following changes:

• Changed devcontainer.json to build local Dockerfile because it's more flexible to customize dev environment for users and it does not take that much time to build anyway.
• Separate Dockerfile for devcontainer because it requires some hacky things only for VS Code.
• Enabled docker in docker feature of devcontainer to run E2E
• Removed devcontainer settngs and extensions from devcontainer.json because a VS Code user usually has their own custom settings for them so I think we don't need to force them to use specific settings.

It would be better to show the specific URL of mcr.microsoft.com/vscode/devcontainers/go:1

Dockerfile and devcontainer.json seem to fine

Others looks good to me.

It works on my apple silicon mac including auto completion of cgo dependencies (e.g. internal/core/ngt tests) and e2e tests.
Will approve this PR after update branch

By apple silicon mac, you mean opening VS Code devcontainer directly from mac os, not something like lima? Which I didn't expect to work because of its archtecture.

@ykadowak yes, directly on macos with docker desktop.

Thanks! LGTM 💯
