doc: Update bug report issue template with new YAML format

[slarse]

There's new templating functionality for issues that uses YAML to produce much better structured forms for issues. I figured we should try it out. One of the biggest perks is that code formatting is automatic, reporters just need to paste in code, no need for backticks.

This can be considered a draft, feel free to suggest changes.

Thanks! I was looking at that every few weeks whenever an issue was opened :P I didn't realize they are out of beta yet.

I have left a few things that came to mind while skimming the new template.

How about adding the used JVM version string as needed information? Otherwise, looks wonderful.

Of course that should be in there as well. It just somehow slipped my mind. Will add.

@MartinWitt Ready for re-review!

LGTM, let's see how the users like it? Always highlighted source code seems astonishing.
Edit: I have merged it now because we can easily change this anytime we want, if we see there is something missing.

Yep. I had a quick peek and it looks pretty reasonable. Perhaps a bit large with all of the different "input, spoon code, output, expected output" stuff.
