Update issue templates [skip ci]

Closes #1375

This commit attempts to clarify the bug report issue template by:
  * Describing what the link to the reproduction step is
  * Adding TODOs to the reproduction script to make it more clear what
    needs to be changed

This commit also updates to use the modern template format, with both a
bug report template and a feature request template.
