### Current Behavior

In localstack, copying an s3 object in place and requesting a checksum causes an error

An error occurred (InvalidRequest) when calling the CopyObject operation: This copy request is illegal because it is trying to copy an object to itself without changing the object's metadata, storage class, website redirect location or encryption attributes.

### Expected Behavior

AWS s3 allows you to copy the object in place and request a checksum.

aws s3api put-object --bucket my-test-bucket --key go.mod --body .\go.mod
{
    "ETag": "\"f65b3f9b21e0c27be3c60df9c1cd87db\"",
    "ServerSideEncryption": "AES256"
}

aws s3api copy-object --copy-source my-test-bucket/go.mod --bucket my-test-bucket --key go.mod --storage-class STANDARD --checksum-algorithm SHA256
{
    "ServerSideEncryption": "AES256",
    "CopyObjectResult": {
        "ETag": "\"f65b3f9b21e0c27be3c60df9c1cd87db\"",
        "LastModified": "2023-04-19T17:09:16+00:00",
        "ChecksumSHA256": "nAPE7pxlr5L1D67nDJa1rwvmU3fKD2SuaUzeyhSR9Vc="
    }
}

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

docker compose up -d

awslocal s3api create-bucket --bucket my-test-bucket

awslocal s3api put-object --bucket my-test-bucket --key go.mod --body .\go.mod

awslocal s3api copy-object --copy-source my-test-bucket/go.mod --bucket my-test-bucket --key go.mod --storage-class STANDARD --checksum-algorithm SHA256


### Environment
