This is a script used in our devcontainer. Joakim wrote it so let him review. I'm fine with making it more generic as long as the devcontainer continues to work 👍

I'm using the dev-container, but i did not clone the repo into frontend, but homeassistant-frontend so workspace folder is not /workspaces/frontend but /workspaces/homeassistant-frontend
