Auto merge of #6963 - ehuss:doc-inequality, r=alexcrichton

Change docs "inequality" for semver requirement.

I can see how "inequality" may be confusing. I considered a few other words ("operator", "range", "relational"), but settled on "comparison" since it conveys that it is *comparing* against a value. npm uses the term "comparator".

Closes #6958
