[BUG] We should give users 400 instead of 500 on OpenSearch errors

[vicilliar]

Describe the bug
When creating an index with bad arguments, these are passed to OpenSearch and caught by their validation, giving Marqo a 400 and the user a 500. Marqo should catch this 400 and return a 400 to the user as well. Could simply be by wrapping this in a try except block: https://github.com/marqo-ai/marqo/blob/mainline/src/marqo/tensor_search/tensor_search.py#L152

Example

mq.create_index("test-index", settings_dict={"index_defaults": {"model": "my-custom-model", "model_properties":{"dimension": "BAD DIMENSION, NOT INT"}}})

Current Output

marqo.errors.MarqoWebError: MarqoWebError: MarqoWebError Error message: {'message': "{'error': {'root_cause': [{'type': 'mapper_parsing_exception', 'reason': 'Failed to parse mapping [_doc]: Unable to parse [dimension] from provided value [wegerg] for vector [__vector_marqo_knn_field]'}], 'type': 'mapper_parsing_exception', 'reason': 'Failed to parse mapping [_doc]: Unable to parse [dimension] from provided value [wegerg] for vector [__vector_marqo_knn_field]', 'caused_by': {'type': 'illegal_argument_exception', 'reason': 'Unable to parse [dimension] from provided value [wegerg] for vector [__vector_marqo_knn_field]'}}, 'status': 400}\nPlease create an issue on Marqo's GitHub repo (https://github.com/marqo-ai/marqo/issues) if this problem persists.", 'code': 'unhandled_backend_error', 'type': 'backend_error', 'link': ''}

This also may be true for other OpenSearch calls (check add docs, search, etc).

@vicilliar please can you share the version of marqo you are using with current version of marqo the error is not reproducible
