Change HumanSize to BytesSize for memory output in docker stats
.
This fix tries to fix the discrepancy between `docker stats` and `docker run` where `docker run` uses RAMInBytes for all memory related inputs but `docker stats` uses HumanSize for all memory related outputs. To be consistent, `docker stats` needs to use BytesSize for all memory related outputs to conform to RAMInBytes in `docker run`. This fix addresses this issue. As BytesSize is used, the test cases needs to be adjusted to match `KiB/MiB/GiB` instead of `KB/MB/GB`. The documentation has also been updated. This fix fixes #21765.
