KAFKA-9634: Add note about thread safety in the ConfigProvider interface (#8205) 

In Kafka Connect, a ConfigProvider instance can be used concurrently (e.g. via a PUT request to the `/connector-plugins/{connectorType}/config/validate` REST endpoint), but there is no mention of concurrent usage in the Javadocs of the ConfigProvider interface. 

It's worth calling out that implementations need to be thread safe.
