fix: copy requested reviewers not reviewers

The current implementation is not aligned with this description. It
copies the currently open review requests and does not request reviews
from those that already reviewed the original pull request. Let's adjust
the name and the description to fit what it does: copy the requested
reviewers not the actual reviewers.
