Update the Roadmap to show correct deployment status of the footer feature on Modern sites

Not sure if this is the right place for this- but the Micrososft 365 roadmap for the SharePoint Footers is wrong.

Roadmap link: ID#33138 (https://www.microsoft.com/en-us/microsoft-365/roadmap?filters=O365&searchterms=footer)

Support Ticket #14767407 identified this as an error in the roadmap, since the feature is not available to standard users yet, but only targeted users.
