Documentation: Example objects contain duplicate keys

[eecavanna]

The "Data" section of https://www.papaparse.com/docs#results contains something that I think was not intentional on the part of the author.

When showing how the header: false behavior differs from the header: true behavior, it shows an example data structure in each case.

In the header: true example (linked below), the objects contains properties that do not have counterparts in the header: false example, and those properties happen to have the same keys as other properties in the same object. I assume this was the result of a copy/paste error at some point.

Lines 768 to 780 in a116779

	// Example (header: true)
	[
	{
	"Column 1": "foo",
	"Column 2": "bar",
	"Column 1": "foo1",
	},
	{
	"Column 1": "abc",
	"Column 2": "def",
	"Column 1": "abc1",
	}
	]</code></pre>

I propose this as a fix:

 // Example (header: true) 
 [ 
 	{ 
 		"Column 1": "foo", 
 		"Column 2": "bar", 
- 		"Column 1": "foo1", 
 	}, 
 	{ 
 		"Column 1": "abc", 
 		"Column 2": "def", 
- 		"Column 1": "abc1", 
 	} 
 ]</code></pre>
