                              String metadataTextKey)

Creates an instance of PineconeEmbeddingStore.

Parameters:

apiKey - The Pinecone API key.

environment - The environment (e.g., "northamerica-northeast1-gcp").

projectId - The ID of the project (e.g., "19a129b"). This is not a project name. The ID can be found in the Pinecone URL: https://app.pinecone.io/organizations/.../projects/...:{projectId}/indexes.

index - The name of the index (e.g., "test").

nameSpace - (Optional) Namespace. If not provided, "default" will be used.

metadataTextKey - (Optional) The key to find the text in the metadata. If not provided, "text_segment" will be used.
