Deprecated Canaries

**Is your feature request related to a problem? Please describe.**

I'd like to display a deprecated warning for canary versions, so that users are encouraged to upgrade to full releases.

**Describe the solution you'd like**
A config option which allows me to [deprecate](https://docs.npmjs.com/deprecating-and-undeprecating-packages-or-package-versions) canary versions, with a configurable message.

**Describe alternatives you've considered**

**Additional context**
