Added workflow to close stale issues & PRs

[TheNova22]

The following is a workflow creation PR that uses actions/stale to mark a "Stale" label and then close it if still inactive.

Necessary parameters are added and the workflow can be added to any repository once merged as follows:

---
name: "Stale Issues & PR Closure"

on:  # yamllint disable-line rule:truthy
  schedule:
    - cron: '0 5 * * *'

    with:
