TS Issues on routerOptions option?

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?
