[Bug] dry_run flag is ignored while updating index by id

[M1ha-Shvn]

Is this a new bug?

• I believe this is a new bug
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

If I call set_metadata index update by id with flag dry_run=True, The index is updated and the response is UpdateResponse(matched_records=None, response_info=None), the result doesn't look obvious.

Expected Behavior

If I call set_metadata index update by id:

• if flag dry_run=True is set, I expect operation to return number of recrods to be updated in UpdateResponse object, but no operations really executed.
• if flag dry_run=False or None is set, I expect data to be updated, and update information returned in UpdateResponse object

Steps To Reproduce

pinecone = Pinecone(... some credentials ...)
index = pinecone.index(name="my_index", grpc=True)
response = index.update(id="some_id", set_metadata={"update": True}, dry_run=True)
print(response)

# Prints UpdateResponse(matched_records=None, response_info=None)
