[Bug] - REST - NoSuchBucketPolicy error returns empty Resource tags rather than BucketName value

[lrm25]

Describe the bug
After sending a GetBucketPolicy command to a bucket without a policy, a direct-to-s3 call returns something similar to this:

<?xml version="1.0" encoding="UTF-8"?>
   <Error><Code>NoSuchBucketPolicy</Code><Message>The bucket policy does not exist</Message><BucketName>versity-gwtest-bucket-luke-four-1</BucketName><RequestId>C8872RVZ17B250QW</RequestId><HostId>aoSKfEAWHTpqZzPb/w9HG0l1vxBjcop8n1m9HopEGMX+q5vZGrCT5w4t6YS6Ik1YBu9dTlSVqiI=</HostId></Error>

versitygw, on the other hand, returns something like this, and doesn't mention the bucket:

<?xml version="1.0" encoding="UTF-8"?>
   <Error><Code>NoSuchBucketPolicy</Code><Message>The bucket policy does not exist.</Message><Resource></Resource><RequestId></RequestId><HostId></HostId></Error>

To Reproduce

1. Start versitygw, e.g.: ./versitygw --access=******** --secret=******** --region=us-east-1 --cert /Users/lukemccrone/devel/versitygw/cert.pem --key /Users/lukemccrone/devel/versitygw/versitygw.pem posix --versioning-dir /tmp/versioning /tmp/gw
2. Create bucket, e.g.: aws --no-verify-ssl s3api create-bucket --bucket versity-gwtest-bucket-one-1
3. Attempt to retrieve bucket policy with the https://github.com/versity/versitygw/blob/test/rest_get_bucket_policy/tests/rest_scripts/get_bucket_policy.sh script. The command should look like: curl -ks -w %{http_code} https://localhost:7070/versity-gwtest-bucket-one-1?policy= -H Authorization: AWS4-HMAC-SHA256 Credential=********/20241120/us-east-1/s3/aws4_request,SignedHeaders=host;x-amz-content-sha256;x-amz-date,Signature=29682d58ee26c75aee5e4bb9829be6d1966801cd73f841fcfa0422217fe94097 -H x-amz-content-sha256: UNSIGNED-PAYLOAD -H x-amz-date: 20241120T125133Z -o /Users/lukemccrone/devel/versitygw/versity-gwtest-files/policy.txt

Expected behavior
Error returns BucketName with value
