npm pkg fix

This was causing a warning during package publication:

> npm WARN publish npm auto-corrected some errors in your package.json when publishing.  Please run "npm pkg fix" to address these errors.
> npm WARN publish errors corrected:
> npm WARN publish "repository.url" was normalized to "git+https://github.com/lucaswerkmeister/m3api.git"

Apparently the npm docs themselves [1], which still list the URL format
without `git+`, are outdated. Lovely.
