In issues, indicate if previously added label has changed name

Problem to solve

In an issue, you'll see a message like " added X label · 2 months ago"; there may be no other label changes listed, and yet X is not in the Labels list. This is because label X has since been renamed to Y.

Proposal

One option: the text of that entry can be updated to "added Edge label which has since been renamed to Quality · 6 months ago"

What does success look like, and how can we measure that?
