Add history link to redirects noted in _compare diff

[seabelis]

When tracing back possible merge errors, or temporarily reverting merges to unblock other reversions, I sometimes need to revert a redirect. Currently the process is to right-click, copy the original work url, paste it into a browser, and add ?m=history. This is tedious when there are many to check. A link to the history would be tremendously helpful.

Describe the problem that you'd like solved

Add a link to version histories from the compare diff views where linked items (typically authors and works) are noted.

Proposal & Constraints

A similar implementation exists when viewing an author merge. https://openlibrary.org/recentchanges/2021/08/31/merge-authors/84543795.

Additional context

Ex, https://openlibrary.org/books/OL24738846M/Slammerkin?_compare=Compare&b=5&a=2&m=diff is an edition history diff view. The edition has been moved from one work ID to another. Having a link to the histories of those work IDs would save a lot of unnecessary typing. Likewise for any authors that would potentially appear there.

The ask is to modify the Diff page to provide an additional link to go to the history page for a work (of type `redirect) instead of a work url which redirects the librarian
