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/need-help.yml
