Print repo and user context for status commands
Closes #262 

This PR adds another line at the top of `gh {pr,issue} status` commands. It informs the user what repo they're running the command in.

It's entirely possible that:

- ~the username is overkill~ took this out as per ampinsk's suggestion
- my colors don't make sense

~Please note that in order to see the "(fork of owner/name)" indicator the parent repo's remote needs
not be named `upstream` or `github`; otherwise, we (intelligently) display status for the parent
repo and report accordingly. This will alert people that they are running status on a fork in the
event their remotes don't line up with what we expect.~

~I'm not thrilled with how I glommed the `parentRepo` field into the payloads but I was trying to
balance not making an extra request with not including more in the payloads than needed. I'm open to
suggestion there.~

no longer displays whether repo is a fork

All of our other commands print enough context that I didn't think they needed updating.

Show the repo you're looking at in `pr status` and any context about forks.

This is both a stopgap for the current base repo determination confusion and a user experience nicety for the future.
Be explicit in pr status about what you are looking at
