Motivation

Use case:
Sometimes I want to create a preview package without publishing it via the next tag. I could publish the package manually, but having this automated would help a ton.

Proposed Solution

Describe the solution you'd like
Instead adding an empty commit with [img:<tag-name>] would be nice. Semantic-release should then create a new release based on it's rules and deploy this under the given tag name to npm. There should not be a GitHub release and no change committed to the repository though. This could also be done completely without semantic-release if it's any easier.
