feature request(git-changelog): use github authors avatars by default

[northword]

Adding on this issue thread, it would be nice if github avatars of commit authors will be used by default instead of manually mapping authors in config.

@northword was this even possible?

Of course, it's achievable. Until the plugin implements it, maybe it could be done by mapping the array in mapAuthors and specifying a username for it?

@taskylizard In addition, this feature must address the question of what we what to use as a GitHub username. Without clarifying this, we might get the wrong user avatar.

What we have now is a manually configured username field in mapAuthors, which by default matches the GitHub avatar when it exists.

The username and email can be read from the Git history, however, in my experience, many of the usernames in the commit history are not Git platform (e.g. GitHub) usernames.

This looks quite complex to implement and support different data sources, and even valuable to have a dedicated package for more universal use cases.
