GitHub issue forms (#4804)

* .github: move pull request template into .github directory

This keeps it out of the root directory. The main intention is
that keeping it out-of-root helps give it less attention which
is enough for the template.

* .github: add a issue form template for the app

This is based on the exisitng issue template of the app. It has
some additional tweaks done to update stale information.

* .github: add some more issue templates

.github/ISSUE_TEMPLATE/feature-request.yml

+        - Please do your best to search for duplicate issues before filing a new issue so we can keep our issue board clean.
+        - Every issue should have exactly one feature request described in it. Please do not file feedback list tickets as it is difficult to parse them and address their individual points.
+        - Feature Requests are better when they’re open-ended instead of demanding a specific solution e.g: “I want an easier way to do X” instead of “add Y”.
