Feedback for dependabot's recreate command

[spenserblack]

It seems like, for a new PR with no additional edits, recreate and rebase are the same. One thing that surprised me is that recreate does not fetch a dependency's release notes again. This was surprising behavior for me, because there was an instance where a dependency's release notes were updated, but I didn't see the updates added to the PR after commenting @dependabot recreate. My interpretation of "recreate" is that everything is recreated, and I'd expect the process for creating a PR and recreating a PR (such as fetching release notes) to be almost identical. But, if I'm not mistaken, recreate really only recreates the initial commit for the PR, erasing additional commits.

To summarize, recreate seems to be only concerned with the PR's commit history, but I expected recreate to also be effective for the initial PR comment, too.
