Done extensive tests on different metrics and checked the distance values against python https://scikit-learn.org/stable/modules/generated/sklearn.metrics.pairwise_distances.html
Verified the support of the new parameter and also the improvement in precision for dotproduct and cosine and the vector_distance values.

Description
This PR adds support for the new effort and distance threshold in generated GraphQL queries for types that have embedding vectors.
Note. There's a breaking change in the resulting computed distance in that for cosine and dotproduct indexes, the computed distance is no longer divided by 2. The results now correctly represent the distances stored in the index.
