Show date-of-creation of an issue/PR on each card

[bipplane]

Is your feature request related to a problem? Please describe.
Issue and PR cards lack the context of its date-of-creation at a glance, as this can only be seen upon hovering on a card, one at a time.

Describe the solution you'd like
Add a footer to each issue/PR card displaying the creation date in a compact format (dd-MM-yy) to provide a better UX for accessing PR recency at a glance.

Describe alternatives you've considered
Using relative time format (e.g. 1 day ago, 3 days ago) instead of date.

@bipplane Thanks for the suggestion. We need to balance utility with reducing noise. If the info is not something the user need not see all the time and only something they would want to see occasionally, a hover over display is better than show it all the time.

Also, the user might want to get alerted to stale PRs (and possibly those created recently) but wouldn't bother about the creation date for other cases. i.e., new and stale annotations could be more useful than showing creation date for all issues and PRs.
