#2247 - autoconfig openai maxSegmentsPerBatch (#97)

## Issue
Continues langchain4j/langchain4j#2248 from Langchain4J, adding new parameter for
EmbeddingModel from OpenAi

## Change
I added new autoconfig field `maxSegmentsPerBatch`


## General checklist
- [X] There are no breaking changes
- [ ] I have added unit and/or integration tests for my change
- [ ] The tests cover both positive and negative cases
- [ ] I have manually run all the unit and integration tests in the
module I have added/changed, and they are all green
- [ ] I have added/updated the
[documentation](https://github.com/langchain4j/langchain4j/tree/main/docs/docs)
- [ ] I have added an example in the [examples
repo](https://github.com/langchain4j/langchain4j-examples) (only for
"big" features)
