Fixes GH-4754 (#4754)

The Pinecone reference docs state that namespaces are not available on the Pinecone free tier. That was true, but now all current Pinecone plans support namespaces on serverless indexes - the free Starter plan allows up to 100 namespaces per index (see the "Object limits" table at https://docs.pinecone.io/reference/api/database-limits).

Changes (docs/comments only, no behavior change):

  • pinecone.adoc — replace the outdated NOTE with current namespace support info and remove the stale // the free tier doesn't support namespaces. comment from the manual-configuration sample
  • PineconeVectorStore — update the Builder#namespace Javadoc, which still referenced gcp-starter; document the actual null handling instead
  • PineconeVectorStoreIT / PineconeVectorStoreObservationIT — refresh the namespace comments that carried the same outdated claim

Verification: ./mvnw -pl vector-stores/spring-ai-pinecone-store package and process-sources -P checkstyle-check pass; Antora docs build renders the updated note. Note PineconeVectorStoreIT already defaults to a unique namespace per run, so any green IT run against a Starter-plan key exercises namespaces on the free tier.

Fixes spring-projectsGH-4754 (spring-projects#4754)

Namespaces are supported on all current Pinecone plans including the
free Starter plan (the pod-based gcp-starter environment that lacked
namespace support has been retired). Update the reference docs note,
remove the stale sample-code comment, and refresh the matching
builder Javadoc and integration test comments.
