Feature Request: more detailed/correct information when package become duplicated

[Bnaya]

Intro: yarn.lock file may contain several versions of the same dependency. When adding/upgrading packages using yarn, you sometimes end up not with an upgrade, but with an additional of another version of the package.

In the current state of this action, when another version is added, it still marks it as updated. I think it will be more correct to mark it as "added" with the new version, and not as update, or created additional kind of indication for that.

I will try to open a PR to emphasis that.

Worth noting: yarn-deduplicate is an important tool that dramatically helps avoiding unneeded duplications (Some duplications are needed) https://github.com/atlassian/yarn-deduplicates
