Improved issues templates (alshedivat#2110)

Since a lot of issues opened are just questions that should be opened as
so, and sometimes the issue template is just not followed, I decided to
make opening new issues a little more "enforced", if not clear.

I based the new templates on the ones from [pytorch
lightning](https://github.com/Lightning-AI/pytorch-lightning/issues/new/choose),
which I think are pretty good. The visuals will only appear after the
merge is processed, but you can have an idea of how it will look like by
checking their templates and how they look.
