INTPYTHON-834 Allow additional arguments to vector_search_index_definition

[barnuri]

This pull request adds support for passing additional vector index options to the vector search index definition and related functions in pymongo_search_utils/index.py. This enhancement makes it easier to customize vector index creation and updates with extra parameters.

Vector index customization

• Added a new vector_index_options parameter to the vector_search_index_definition, create_vector_search_index, and update_vector_search_index functions to allow passing extra options for vector index configuration. [1] [2] [3]
• Updated the construction of the vector index definition to include any provided options from vector_index_options, enabling more flexible index setup.
• Ensured that the new vector_index_options parameter is properly forwarded when creating or updating vector search indexes, maintaining consistency and ease of use. [1] [2]
