- Explicity label both category and topics to be completed with a link
to appropriate section of the metadata docs
- Request tests for example queries and some negative samples.
- Point to metadata docs to help fill out section.
- Reorganize metadata into same order as docs.
- Remove "icon_url" and "source" which do not generally apply to
Goodies.
- Better example strings for the `attribution` section.
- Use "guard" before "work" in example code.
There will likely be some debate about whether or not to include the
`is_cached` value, but I like making it explicit even when there is
a default.
On the `answer_type`, the tests as produced by `duckpan new` could
not pass. It might not be entirely clear to the new developer how to
add the `answer_type` and fix them.
