Description
This is a limitation on github urls, seems about 8195 (including https://github.com)
here
Expected behavior
I think maybe we can copy the body to clipboard and open a url like this
https://github.com/sindresorhus/np/releases/new?body=<!--%20paste%20your%20release%20notes%20here%20-->
Maybe new-github-release-url should also throw an error.
