[RFC] Use profile link of a contributor in the CHANGELOG

[pedro-psb]

Problem

The new release script introduced in #1078 generates a changelog without the link to the author github profile:

dependabot alert 21 about Django (on tests) (#1067). By Bruno Rocha.

Proposal

I want it to be rendered as:

dependabot alert 21 about Django (on tests) (#1067). By [Bruno Rocha](https://github.com/rochacbruno).

Additional Context

The reason the github link is not fetched is because git-changelog only uses information available in git (name and email) in the commit range to be released.

To fetch the github link, we could hit the github API:

1. Fetch a list of users from latest release to the current one
2. Map user-email: url
3. Link git user.email with github url using that map

We may have to open a PR in git-changelog to support this. Possible approaches to present to the project:

• add the GitHub API fetch inside git-changelog
• make it possible to provide a map (user-email: url), which should be available internally the template.
  • This map could be a simple toml file
  • We should generate this file externally using the GH API.

Possibly, we could integrate that solution with fixing the update_contributors workflow, which is broken.
