The name "text embedding" is used in many places where dense vector embeddings are handled, despite the type of the embedding vector not being exclusive to text embeddings. For example, image or multimodal embeddings may also produce a dense vector. To allow future reuse of classes related to dense vectors with multimodal embeddings, the naming is being changed to the more general "dense embedding". Classes which explicitly relate to text embeddings are not being renamed. This rename is internal to the code only and does not change the name of any JSON objects which currently use "text_embedding", as doing so would be a breaking change. - For everything not exclusively related to text embedding, rename classes, methods and variables to use "dense embedding" instead of "text embedding" - Use correct class name in ElasticTextEmbeddingPayload.TextEmbeddingFloat.PARSER - Correct the javadoc in DenseEmbeddingBitResults

There was a problem hiding this comment.
This parser was previously using the incorrect class name, which would have led to any errors encountered when parsing to report the wrong class.
