Always create new comment for visibility

[ellatrix]

What?

Always create a new comment at the bottom of the PR.

Why?

To increase visibility of the comment, and make it harder to miss.

The problem with editor the comment is that is maintains the same position on a PR.

• When the time of merging comes, it's easy to forget adding the props, because the message is not directly in front of you.
• When remembering to add them, you have to scroll back and find the comment.
• Often, on much discussed and reviewed PRs, this comment will disappear because Github hides/collapses older comments.

How?

Instead of editing the previous comment, delete it. Then always add a fresh comment, which will appear at the bottom.

@ellatrix and I chatted about this on a few occasions. The intention here was to improve maintainer workflows and avoid forgetting to add props when merging. But this approach would result in many more notifications, especially on PRs with high levels of activity.

Going to close this out.
