consistently use `Timeago` component to humanize timestamps

[annthurium]

We have this sweet Timeago component that humanizes a timestamp, and then keeps that data up to date.

I did not know about Timeago, when we were making the CommitDetailView and the PullRequestCommitView. It would be good to make those components use Timeago, and also see if there's anywhere else that needs to be cleaned up.

Hi, I would like to start contributing and this seems like a good issue to start :smiley: Would it be ok if I tried to have a look at it? The two views that don't use Timeago referenced in the description seem pretty straight forward to fix but looking for other files is the tricky part.

@MiguelSilva96 Just go for it. Its better to open PR's on this repo rather than comment inside issues.
