feat: add context menu to open issue/mr in browser
Implements #734
MR Details
This adds a new context menu "Copy link to item" for both issues and MRs. Using this, user can copy to their clipboard the corresponding issue / MR.
This is my first contribution on this repo - I took !776 (merged) as an example. I wasn't sure how to name the context menu item. My apologies if I did something wrong!
