feat(version): add flag to include changelog commit author, close #248

[ghiscoding]

Description

Add a flag --changelog-include-commit-author to optionally include every commit author name in the changelog when using conventional-commits, this in terms is allowing us to see all PR contributors.

Supersede previous PR #249 to fix issue #248

Motivation and Context

new feature related to the issue #248, please note that this implementation is not exactly pretty code but at this time conventional-changelog lib doesn't provide any easy way to add the commit's author name directly (as requested in this issue), this PR will do that (even if it's a bit hacky). The hacky part is that conventional-changelog lib does provide the format argument (which is supposed to git log pretty format) but it then calls its own template parser which interfere with the git log format and that plays with the actual string output, basically any of the format argument(s) provided will end up being part of the commit url because of that said template parser, so we then have to pull any extra string argument (like the author that we add in the format) and move them outside of the commit url to avoid breaking the commit url.

Let's take this code example, the commit url in changelog will end up looking like this (with defined tokens or our own)
[e123b32](http://github/..../e123b32<<author=Reno Bot>>))
we will then extract the author and move it outside the commit url, then transform it into something readable like this:
[e123b32](http://github/..../e123b32)) (@Reno-Bot)

For a final live example, executing a new version of Lerna-Lite in dry-run mode, we get the following with/without commits authors

without commit's author (before new feature or when new flag isn't provided)
