What does this Pull Request accomplish?

This PR replaces our old issues template with a new one.

---

Currently, when I create a new issue for the repo, it's blank, despite our ISSUE_TEMPLATE.md. This seems to be because we've been using a legacy issue template feature and GitHub probably turned it off (although the newer feature is supposedly in beta).

Following the instructions here I went through the steps to setup a bug report template (and copied our ISSUE_TEMPLATE.md for the content.

I also configured it to auto-assign the 'bug' label.

This PR will commit the new issue template and delete the old one.

List issues fixed by this Pull Request below, if any.

I wonder if we should update the template to mention our security policy. A reminder to users before they create a public bug to not report security issues through public bugs.

I wonder if we should update the template to mention our security policy. A reminder to users before they create a public bug to not report security issues through public bugs.

Probably not necessary, given what now pops up when you go to create an issue.

The option to report a security vulnerability is right there, so that should be a solid enough nudge.
