JSSDK 0.5.2 release

Hi everyone, we released a minor update for JSSDK today. This update fixed some critical issues that arose during the Hackathon.

• fix: The PinkLoggerContractPromise cannot only list records that are related to a specified contract.
• fix: The final InkQuery sent through PRuntime is invalid when manually connecting to a specified PRuntime because it lacks the systemContract information.
• fix: The gas price and storage deposit price are missing from the cluster information when connecting to the specified PRuntime.
