issues: re-order issue template for more clarity

Triaging issues has become a little challenging since the meat
of the information is below a large amount of unstructured
command line output. These changes add a description and move
the reproduction and expected/received results above the
unstructured output.

This should help for initial triaging, as well as self-triaging.
