TS Issues on routerOptions option?

[dsolis]

Hello guys,
I'm trying to use the newest version of fastify 5.5.x and trying to remove the warning:

The router options for ignoreTrailingSlash property access is deprecated. Please use "options.routerOptions" instead for accessing router options. The router options will be removed in `fastify@6`.

But when initializing the object with

routerOptions: {
    ignoreDuplicateSlashes: true,
    ignoreTrailingSlash: true,
}

the property is not found on the type FastifyServerOptions

Is this a bug with the new version?
