Show original post date/time on edited posts

For backend issues, use lemmy

Is your proposal related to a problem?

At the moment, timestamps on edited posts are wonky (see #437).
It would be nice to have both the original post date and the latest edit, instead o just the latest edit (or whatever was intended :P)

Describe the solution you'd like

You could put a little "post" icon followed by the original post date, then a · or similar, followed by what we have rn (a pencil icon followed by the edit date).

Describe alternatives you've considered

You could also just have a single thing that shows both dates on the tool-tip.

Additional context

Issue #437 is related. Also this screenshot shows the UI element I'm referring to in my proposed solution.

Yep, It'd be possible to show both the edited and created time on the tooltip, on two separate lines.

But as for the icon and main part, I'd like to leave only the edited time, not both, as it'd take up too much space.
