add a link to merged works

[BearSunny]

Closes #10714

This PR achieve to link each merge request listed to the resultant work.

Technical

I only added a link to $review_url by setting <a href="$review_url" class="mr-title-link">. This should create a link to the resultant work for now. If there's anything more that should be done, please leave a feedback. Thank you!

Thanks @BearSunny! I noticed an issue with the requirements, and have suggested a change that should correct the problem (some more background information is included in the comment with the suggestion).

Could you test this change, and commit it if it works? You can follow the steps outlined here to populate your local development instance with a few merge requests (some open, some closed).

Thank you for your feedback @jimchamp! I have tested the change and it works perfectly so now only closed merges are linked with the resultant works. I have also committed the change.

[jimchamp]

Thanks @BearSunny! Have confirmed that the links are appearing only for closed merge requests.

Although the links are present on closed merge requests, these pages are only accessible for patrons with the following privileges:

• librarian
• super-librarian
• admin

I think that this is fine for now, as the merge request table isn't navigable from the UI unless the patron is a member of any of these groups. When/if we expose this table to all patrons, we'll probably want to make the following changes:

1. Remove the merge buttons from merge UIs for patrons who click this new link. We can probably use a query parameter for this.
2. Lift the access restrictions to the author and work merge pages.
