Implement Stale PR Handling and Update Stale Issue Handling (#2151)

* Implement Stale PR Handling and Update Stale Issue Handling

Use actions/stale to perform the following actions twice daily:

 - Mark PRs that haven't been touched for 30 days as stale.
 - Close PRs that have been marked stale for 7 days without an update.

Update stale issue handling:
 - Mark issues that haven't been touched in 6 years as stale (increased from 1 year).
 - Remove inputs section and directly specify values, as the inputs section was not being properly referenced and default values were being used.

* Allow manual triggering of the action.
