Chroma Spring Boot Starter

[emredmrcan]

Issue

Fixes langchain4j/langchain4j#2205

Change

A new Spring Boot starter module named langchain4j-chroma-spring-boot-starter was added.
This includes creating auto-configuration classes and properties to facilitate easy setup and management of Chroma within the LangChain4j.
The root pom.xml was updated to include the new module.
An import file for auto-configuration was created to facilitate Spring Boot's configuration process.
