✨ Copy Link to Code

### Description

It would be awesome if CodeEdit could copy links to code when the workspace has a remote on GitHub.

I'd imagine it's on a key command like Command-shift-c as well as a button in the file inspector. It would only be abled when source control is on a branch that is tracked by a remote on GitHub. Then we can craft a link to the correct branch/file/lines using GitHub's permalink format.
