feature apt-get-packages fails with devpod

[behrica]

What happened?
Having this snipped in devcontainer.json

    "ghcr.io/devcontainers-contrib/features/apt-get-packages:1": {
      "ppas": ["ppa:ubuntuhandbook1/emacs"],
      "packages": "emacs,rlwrap,fonts-hack"
    }

fails with error:

19:09:08 info #11 134.8 add-apt-repository -y ppa:[ppa:ubuntuhandbook1/emacs]
19:09:08 info #11 134.8 Unable to handle repository shortcut 'ppa:[ppa:ubuntuhandbook1/emacs]'
while it does work in codespaces

Local Environment:

• DevPod Version: 0.5.4

• Operating System: linux

• ARCH of the OS: i386

• Local/remote provider: docker
