If woodpecker-ci/woodpecker#916 lands, this repo need some adjustments ...

@s00500 your feedback would be welcome there too ;)

This looks like a great change, I can update the repo on the weekend if I find a bit of time

Thanks, also for your initial work 😉. I am so excited for woodpecker-ci/woodpecker#915 which will allow us to configure extensions (like config, secrets & registry service) on a per repo base.
