feat: add the ability to create a PR with the incoming changelog

[Barbapapazes]

Hello,

This PR follows https://github.com/nuxt/nuxt/issues/20675.

It's a first draft because I'm not sure on how we must handle the PR. In fact, have we to reuse code from the release, create a new condition or a new command?

Also, we need to:

• [ ] Add the base branch into the config file (or maybe there is already a base branch and I don't see it)
• [ ] Add a way for the user to provide a template for the changelog header
• [ ] Add a way to customize the branch name
• [ ] Add a way to change the user that create the commit (name and email)

Support for workspace will coming after #18 is finished.

I think for first step, we can introduce a updateGithubIssue utility, it can search for github issues and update first with v{x.y.z} title or create a new one. Dealing with branches for PR can be next step :)

Ok, if I understand well, you can to have a command to add changelog to an issue and another one to add changelog to a PR which also update package version?

@pi0 can you tell me if direction is correct before I continue to create code?

Still wip but I want to be sure that I'm not doing something wrong!
