Instead of using CorsConfiguration on the bucket, you need to attach a bucket policy to it. Try the following:

Resources:
  AttachmentsBucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: range-picker-bucket-${self:custom.stage}

  AttachmentsBucketAllowPublicReadPolicy:
    Type: AWS::S3::BucketPolicy
    Properties:
      Bucket: !Ref AttachmentsBucket
      PolicyDocument:
        Version: "2012-10-17"
        Statement: 
          - Effect: Allow
            Action: 
              - "s3:GetObject"
            Resource: 
              - !Join ['/', [!Ref AttachmentsBucket, 'public']]
            Principal: "*"
