Increase stale issue time & enhance stale bot config

[mhucka]

Until we have time to revisit the auto-closing policy (issue #6866), we decided we could increase the duration before issues and PRs are marked as stale and closed. This PR changes the durations to 90 days before marking as stale and 60 days before closing. It also adds a couple of enhancements:

• Revised and hopefully somewhat friendlier messages left as comments
• The addition of a manual run trigger, to allow manual invocation and dry runs

LGTM, but please confirm the cron-started workflow is run as non-debug.

[pavoljuhas]

IIUC, the debug mode is not in effect when this get started on cron schedule, can you please confirm?

[mhucka]

That's right; that setting around lines 10-11 is only for when the workflow is invoked manually, via workflow_dispatch. Otherwise, on cron schedule, the value of inputs.debug is never set and is therefore an empty string. In the workflow body, the debug-only flag for actions/stale defaults to false:

debug-only: ${{inputs.debug || false}}

My thinking is that it's rare for someone to want to invoke it manually, and when they do, it's mostly likely because they're debugging something, so the natural default in that case is to turn it on. Plus, it has the advantage of erring on the side of caution, by requiring confirmation for taking action.

I think we should flip these. The issue / PR should become stale before closed.
NVM - after reading how those values work, sorry about the noise.
