[Bug]: Enhanced JSON Output action output does not match wiki example

### Apache Hop version?

2.3

### Java version?

jdk-16.0.1.9

### Operating system

Windows

### What happened?

I have rebuilt the scenario as described in https://hop.apache.org/manual/latest/pipeline/transforms/enhancedjsonoutput.html but my output is different from the wiki page. I get
`
{
"result" : [ {
"campo2" : "F",
"campo3" : 5
}, {
"campo2" : "F",
"campo3" : 6
}, {
"campo2" : "V",
"campo3" : 6
}, {
"campo2" : "B",
"campo3" : 7
} ]
}
`

### Issue Component

Component: Actions

Start with the Enhanced JSON Output action example at the linked manual page and reproduce it using the attached json enhanced test.zip HPL file on Apache Hop 2.3. Compare the generated JSON with the wiki example and determine whether the action or its documentation is inconsistent; done means the reported discrepancy is resolved or the documented expected output matches actual behavior.
