Array slicing does not follow the syntax in https://goessner.net/articles/JsonPath/

[khairihafsham]

Problem:

$..book[:2] produces 3 elements, where according to https://goessner.net/articles/JsonPath/, it should produce 2 elements.

$..book[::2] produces 2 elements and consistent with the documentation for this repo.

Is this expected?

Reproduction Steps:

require 'jsonpath'

json = <<-HERE_DOC
{"store":
  {"bicycle":
    {"price":19.95, "color":"red"},
    "book":[
      {"price":8.95, "category":"reference", "title":"Sayings of the Century", "author":"Nigel Rees"},
      {"price":12.99, "category":"fiction", "title":"Sword of Honour", "author":"Evelyn Waugh"},
      {"price":8.99, "category":"fiction", "isbn":"0-553-21311-3", "title":"Moby Dick", "author":"Herman Melville","color":"blue"},
      {"price":22.99, "category":"fiction", "isbn":"0-395-19395-8", "title":"The Lord of the Rings", "author":"Tolkien"}
    ]
  }
}
HERE_DOC

# should produce the first 2 elements, but got 3 instead
puts JsonPath.new('$..book[:2].price').on(json)```

I've created a PR. Not sure if it is appropriate. But, please have a look and comment if I need to make improvements.
