Placement setting has no effect when creating a new key-value bucket

[hungiito]

Observed behavior

placement parameter has no effect when creating new key-value bucket. For example:

Expected behavior

Key-value bucket to be placed in expected regions (specified by placement tags)

I tried adding placement=config.placement here and successfully created the bucket in the correct region.

Steps to reproduce

Script to create new key-value bucket

client = ...
key_value = await client.jetstream.create_key_value(
    bucket="system",
    placement=Placement(tags=["geo:us-west", "cloud:aws"]),

nats kv info says that the stream is in another region (eu-west-1 in my case)
