issuse/PRs, configures 'exempt' labels, and additionally the number of
days before a issue is marked stale/closed.

Our current templates do not use the latest GitHub templates, so this updates them. I have adjusted and removed some wording to make the template simpler, as I have found some users neglect to fill in the template, or partially fill it in. I hope this helps with the bug reporting process.
