[Bug] - The `EntityTooSmall` error should include `ProposedSize`, `MinSizeAllowed` in the xml response.

[niksis02]

Describe the bug
The EntityTooSmall xml error response is missing the ProposedSize, MinSizeAllowed properties.
Note the currently the error appears in 2 scenarios.

1. Browser POST request file size does't match the content-length-range policy condition
2. One of multipart upload parts size is less than 5Mib.

In first case the error is missing only ProposedSize, MinSizeAllowed.
e.g.

<?xml version="1.0" encoding="UTF-8"?>
<Error><Code>EntityTooSmall</Code><Message>Your proposed upload is smaller than the minimum allowed size</Message><ProposedSize>20</ProposedSize><MinSizeAllowed>20000</MinSizeAllowed><RequestId>DMZAWQJW825GKGN5</RequestId><HostId>uyoDb9TVmyHk/GMgSD2bMva9ylQ9/LqM2zydjXeVFlE/e/xifXDnxGCuMhgKa19wHSCw0rmeY8h8e4oynVsiSXbROKiIo/JG</HostId></Error>

In the second case, versitygw is missing ProposedSize, MaxSizeAllowed, PartNumber, ETag.
e.g.

<Error><Code>EntityTooSmall</Code><Message>Your proposed upload is smaller than the minimum allowed size</Message><ProposedSize>60166</ProposedSize><MinSizeAllowed>5242880</MinSizeAllowed><PartNumber>1</PartNumber><ETag>98d3f377a91dbe9c82408ee34ee01ced</ETag><RequestId>6PMZGZYM3HVNJX30</RequestId><HostId>xY4MHxD9qyQ8Ptvr95gfBmgL5QNHJy7OtP5yr7eHzEunpH0iStKn+j+qwIgqfiR9bFIfWIGpe79d9VEKPJD03nTThjLd3yRN</HostId></Error>

To Reproduce

aws s3api create-bucket --bucket test
aws s3api create-multipart-upload --bucket test --key mp
aws s3api upload-part --bucket test --key mp --upload-id <uploadId> --part-number 1
aws s3api upload-part --bucket test --key mp --upload-id <uploadId> --part-number 2
aws s3api complete-multipart-upload --bucket test --key mp --uploadId <uploadId> --mulitpart-upload file://mp.json

Where mp.json is:

{
  "Parts": [
    {
      "ETag": "d41d8cd98f00b204e9800998ecf8427e",
      "PartNumber": 1
    },
    {
      "ETag": "d41d8cd98f00b204e9800998ecf8427e",
      "PartNumber": 2
    }
  ]
}

Expected behavior
The object POST case should include ProposedSize, MinSizeAllowed and the multipart upload case should include ProposedSize, MaxSizeAllowed, PartNumber, ETag in the EntityTooSmall xml error response.
