This adds support for #559. I tested using [this .woodpecker.yml](https://git.exozy.me/Ta180m/Hello-world/src/branch/main/.woodpecker.yml) on my self-hosted [Woodpecker instance](https://ci.exozy.me/Ta180m/Hello-world). I was also able to get this to build [Hugo websites](https://ci.exozy.me/Ta180m/howtuwu/build/1). It's currently very simplistic but works! close #559
