Update devcontainer

Explanation

Update devcontainer definition:

• Use "standard" devcontainer base image that includes make
• Use devcontainer features to install docker, kubectl, minikube, kind, helm and go
• Switch user to vscode (default) instead of root in the container

This fixes the issue that make was not installed and also simplifies the setup by making use of available devcontainer features instead of rolling our own.
