Incorrect return value of Kruskal

[tequ1lAneio]

Hi, @loiane

I found an unexpected result of Kruskal for getting MST.
see https://github.com/loiane/javascript-datastructures-algorithms/blob/main/examples/chapter12/07-Kruskal.js#L18

When running the code above, the return value is [2, 2, 4, 2, 2] instead of the expected result [2, 2, 2, 2, 2].
Could you take a look at it? Thanks!

Prim and Kruskal can have different results. It all depends on the algorithm, both would be valid results.
