fix(openai): Simplify embeddings input handling

[alexander-alderman-webb]

Description

Do not handle parameters which are not declared for Embeddings.create. See

https://github.com/openai/openai-python/blob/acd0c54d8a68efeedde0e5b4e6c310eef1ce7867/src/openai/types/embedding_create_params.py#L14

Do not check for the Omit sentinel when setting the request model, because the model is required.
Replace set_data_normalized with set_data for the request model, since the model parameter is declared to be a string.
