Describe the situation after applying the recipe

src/main/resources/config/application.yml

server:
  port: ${PORT:8080}

@timtebeek I have the start of a recipe properties->yaml and some infrastructure to support conversion either way.

I am reluctant to contribute it back (especially in this library).

https://github.com/tkvangorder/rewrite-sandbox/blob/main/src/main/java/org/openrewrite/contrib/convert/ConvertPropertiesToYaml.java

If you want to take the time to copy the code over, go for it.

Much appreciated, thanks! I'm out for the next two weeks, but could be interesting to take on after. Or anyone else that wants to step up in the mean time.
