`Warning: Unexpected input(s) 'greater-version-only'` on action run

[WillsterJohnson]

According to the readme I can pass a boolean greater-version-only, which ensures that if the latest version is, for example, 1.2.5, I cannot publish 1.2.4, even if 1.2.4 has never been published.

When running in a workflow, I get the following warning;

Warning: Unexpected input(s) 'greater-version-only', valid inputs are ['token', 'registry', 'package', 'tag', 'access', 'dry-run', 'check-version']

Here's the workflow run I'm referring to.

Is greater-version-only a valid option, and the action is just missing something in the warning condition? Or does that config option actually not exist, and is incorrectly documented?
