📚 Description

Added styles for <Slider orienation="vertical" />.

The orientation property is not mentioned in the documentation, but radix-vue supports it, and the property is inherited. With this update, if someone uses the orientation="vertical", it will render the <Slider /> properly.

Should we offer generic styles based on orientation?
