As additional question: how to patch runtime definition within project configuration? So let's say we would like to have completely custom ruby-build version and download path.

If I follow this https://docs.trunk.io/cli/configuration/runtimes, it should be enough to go with:

runtimes:
  definitions:
    - type: ruby
    ...

It could be nice to mention this feature in documentation.
