I created a new package using `nimble init` and once it was ready `nimble publish` and put it on github: [diff](https://github.com/mark-summerfield/diff) but on the [nimble directory](https://nimble.directory/pkg/diff) it is listed as "no version" and "install test failing", and the link to "Hosted docs" leads to an empty page.
How do I fix these things?
