fix: pinecone serialization issue (#2394)

Browse Source 
This fixes the serialization of the Pinecone destination connector.
Presence of the PineconeIndex object breaks serialization due to
TypeError: cannot pickle '_thread.lock' object. This removes that object
before serialization.

### Fixes
* **Fix GCS connector converting JSON to string with single quotes.** FSSpec serialization caused conversion of JSON token to string with single quotes. GCS requires token in form of dict so this format is now assured.
* **Fix the serialization of the Pinecone destination connector.** Presence of the PineconeIndex object breaks serialization due to TypeError: cannot pickle '_thread.lock' object. This removes that object before serialization.
## 0.12.0
