Initial ISSUES_TEMPLATE

* Adopting a similar system to *@octokit/octokit*
* Since this needs to be spelled out... spelling it out.
* Embedded Unicode is prohibited *(is anyhow in STYLEGUIDE.md) in these files as a potential crash of git-scm can occur on some systems.
* GH discussions are still in Beta but used "Community-driven" for OUJS vs whatever nomenclature we use if we turn that feature on.

Applies to OpenUserJS#249 OpenUserJS#1792
