Allow navigation to "Manage Merge Request" Page from Profile Overview

Currently, the only way to get to the "Manage Merge Request" Page is through the link in the Merge Request. This isn't super obvious, due to the link text not explicitly mentioning that that page exists. It would be nice to have a button on the Contributor Platform itself to open that page.

At least for me, the overview on a users profile seems like the most logic place to put it (see screenshot), but I'm open to other places if they make more sense
