fix(recommend): update recommended-for-you model type

[raed667]

When calling getRecommendations we need to make sure that the user doesn't have to pass objectID for the model recommended-for-you.

Otherwise this error will occur:

Property 'objectID' is missing in type '{ indexName: string; model: "recommended-for-you"; fallbackParameters: RecommendSearchOptions | undefined; queryParameters: (RecommendSearchOptions & { ...; }) | undefined; maxRecommendations: number | undefined; }' but required in type 'RecommendationsQuery'.

The fix should be a patch since the model is not publicly available yet.
