Description

Would be great if you could create a custom plugin for stylelint that adds support for your custom rules; for example, making font-range a known property for the property-no-unknown rule.

Research direction
The issue requests a custom Stylelint plugin to add `font range` as a known property for the `property no unknown` rule. To implement, first understand the Stylelint plugin API (see https://stylelint.io/developer guide/plugins). Then examine existing plugins or the `property no unknown` rule source to see how properties are whitelisted. The plugin should export a rule that extends `property no unknown` with `font range` in the `properties` option. Test the plugin with a sample CSS file.
