Approve / Reject buttons should show your current approval status #2537

Sometimes I double check if I've already approved a PR or if it was waiting for changes (with a rejection) or if I just made comments. It would be nice to not have to switch back to the comments page to see what the PRs current approval status is.

I was thinking if you already approved the PR, the 'approve' button appeared already pressed. Alternatively it would be nice to see the current 👍 👎 stats much like you see reactions to the left of the buttons:

1 (you) 👍 1 👎 [Comment] [Request Changes] [[Approve]] or [Comment] [Request Changes (1)] {Approve (you+1)}
