Subject: [PATCH] chore(Changelog): show who created the pull request that was
 merged (#329)

* feat: say who submitted the PR that was merged

* fix: actually make the changelog generation work

* chore: cleanup

* chore: safety

* fix: fetch PRs in a better way, and replace usernames with diff casings correctly

* fix: only fetch PRs if GITHUB_TOKEN is in the env

* fix: add github token to branch creation

* fix: actually patch the module on install

* chore: cleanup some more of the PR

* chore: make the script more agnostic

* chore: cleanup package-lock

* chore: use split instead for more readable code
