Use new GitHub issue forms?
Github recently released a beta for issue forms (https://github.blog/changelog/2021-06-23-issues-forms-beta-for-public-repositories/). Scipy already has an open pr to use these to replace existing issue templates (https://github.com/scipy/scipy/pull/14493)

Seems like a good way to improve issue quality, while also making writing issues easier for users (through improvements like built-in code formatting).
