test(client-s3): use chunk size of 8 KB

[trivikr]

Issue

Internal JS-5678

Description

Changes chunk size in E2E tests to 8 KB.

From S3 documentation

The chunk size must be at least 8 KB. We recommend a chunk size of a least 64 KB for better performance. This chunk size applies to all chunks except the last one. The last chunk you send can be smaller than 8 KB. If your payload is small and can fit into one chunk, then it can be smaller than the 8 KB.

Testing

Before

...

     ❯ PutObject (1)
       × should succeed with Node.js readable stream body
