2.0 release

[stellasia]

We are working on a 2.0 release that will contain the following improvements and breaking changes:

Improvements

• Improved pipeline for KG builder (better performances)
• KG builder pipeline and components production-ready (not in experimental namespace anymore)

Breaking changes

• Legacy Pipeline object will be removed
• Pipeline from config won't be available in 2.0 - can be reintroduced later if there is interest in this feature
• Legacy LLMInterface will be removed in favor of the LLMInterfaceV2
• VertexAILLM and VertexAIEmbeddings will be removed as they rely on a deprecated library. Use GeminiLLM and GeminiEmbeddings instead.
• Remove id from the GraphRAG search method
• Switch return_context default value to True
