Add additional information to created issue

[ahatzz11]

It would be awesome to see some additional metrics in the generated report! Here's a list of ideas, days since:

• Last Release
• Last PR made

Having these be configurable, with something like the following would be awesome:

DAYS_INACTIVE_METRICS: 'push, release, pr'

@ahatzz11, what other actions can you think of?

[AlexanderLanin]

Less interesting for open source, but for enterprise organizations it would be nice to print the owner and the last n people who have pushed.

Potentially even creating an individual issue per stale repository (in the action repo / in the inactive repo), assigned to the owner of that repository.

This issue is stale because it has been open 21 days with no activity. Remove stale label or comment or this will be closed in 14 days.
