fix output.script syntax in HTTP requests examples

[fardage]

Description

Fixes incorrect syntax in the HTTP requests documentation that causes a runtime error.

Problem

The documentation currently shows:

output.script.result = json(response.body).myField.mySubField

This causes the following error:

TypeError: Cannot set property "result" of undefined to "xyz"

Solution

Changed to the correct syntax:

output.script = json(response.body).myField.mySubField
