`ChecksumCRC32` `get_object` field is not present after uploading via a presigned URL with `x-amz-checksum-crc32`

When uploading an object via a presigned URL with the `x-amz-checksum-crc32` field set, based on the documentation I assumed the `ChecksumCRC32` field would be available in a [get_object ](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3/client/get_object.html) call, but it doesn't appear to be there.

## Expected Behavior
When uploading an object via a presigned URL with the `x-amz-checksum-crc32` field set, the `ChecksumCRC32` should be present in the `get_object` response for that object.

## Current Behavior
The field does not appear to be there.

## Possible Solution
Possibly I'm doing something wrong, although the logs show that Minio is receiving the CRC as it's sending it back in response to the POST.

If I'm not doing something wrong and I'm interpreting the `get_object` documentation correctly, then the `ChecksumCRC32` presumably needs to be added to the `get_object` response.

## Steps to Reproduce (for bugs)

* Start Minio
```
MINIO_ROOT_USER=admin MINIO_ROOT_PASSWORD=password ~/minio/RELEASE/2024-08-17T01-24-54Z/minio server ~/minio/data
```
* Use the method of your choice to create a bucket called `test`
* Execute the following Python code
```python
$ ipython

It seems to be returned with the original POST but not with the `get_object` request.

## Context
I'm trying to download objects from Minio and ensure that data integrity is maintained via a CRC check.

## Regression
I don't know; I have no reason to think so.
