Add classname to RouteLongName component

[alec-georgoff]

Description:

Adds the route-long-name class to the RouteLongName component in RouteBlock, allowing configurations to selectively style the component without relying on nested selectors.

PR Checklist:

• Does the code follow accessibility standards (WCAG 2.1 AA Compliant)?
• Are all languages supported (Internationalization/Localization)?
• Are appropriate Typescript types implemented?

Is there any way we can contextualize the class name? (route-block-route-long-name or similar)
