Update Github issue templates to use issue forms

Here we have updated the Github issue template files to utilize forms.
This involves using YAML configuration files instead of markdown. This
should make issue submissions easier for users and will ensure users provide
the required information.

Note that issue forms are not supported for pull requests currently. The
pull request form here has been cleaned up slightly.

Addresses feature request geoschem/geos-chem#1831.
