`changelogen release-ci` to auto release (`pkg.pr.new`)

[pi0]

Describe the feature

We can introduce changelogen release-ci that triggers release on each CI run.

pkg.pr.new could be first provider but i am thinking that we design internal impl to be provider agnostic. (if defined as a direct fetch specification that would be perfect, we can use npm pack + POST)

/cc @Aslemammad if you had time before me to pick on this, i would love to have it 🙏🏼
