Update OpenAI embeddings stripNewLines to be default false (#3612)

* Updating the default value for `stripNewLines` to `false` in the `openai` embeddings. As removing newlines was beneficial for `V1` models (or `-001`), but should not be mandatory for `V2` models (or `-002`). This is explained in openai/openai-python#418 (comment)

Therefor updating this field to be in line with the default set model `text-embedding-ada-002`.

Also the langchain python library only enables this for `-001` models: https://github.com/langchain-ai/langchain/blob/c0f4b95aa9961724ab4569049b4c3bc12ebbacfc/libs/langchain/langchain/embeddings/openai.py#L466

* Reverting the default value, so it's `false` by default again.
Marked with a comment to indicate this should be changed in a future minor release.
Referenced the PR, as it contains the necessary information as to why this should be updated.

* Resolving conflicts, adding changes again to new location.
