Clarified and fixed some horrific errors (#22355)

* Clarified the sentence about zero indexing and that any data type can be stored in an array
* Added spacing between elements
* Fixed declaration format `new nameOfArray[numberOfElements](vals)` is definitely not a thing it should be `new dataType [numberOfElements](vals)`
* Added shorthand definition
* Removed claim that you are storing an array in another array by assigning an alias to it

 ## Rules of Arrays
 
-Arrays start from zero. The first element of an array is 0, the second element is 1, the third element 2, and so on.
+Arrays start from zero. That is to say that the first element of an array is indexed as 0, the second element is 1, the third element 2, and so on.
