Improve "Creating an Empty Array" section in Language Guide

- Highlight empty array literals (`[]`) as the preferred method.
- Add initializer syntax (`[Type]()`) as an alternative.
- Reorganize examples to reduce redundancy and improve clarity.

 ### Creating an Empty Array

+You can create an empty array in Swift using one of two approaches:
+
+If the context already provides type information,
+such as a function argument or an already typed variable or constant,
+you can create an empty array with an *empty array literal*,
+which is written as `[]`
+(an empty pair of square brackets):
+
+```swift
+var someInts: [Int] = []
+print("someInts is of type [Int] with \(someInts.count) items.")
+// Prints "someInts is of type [Int] with 0 items."
+```

+  ```swifttest
+  -> var someInts: [Int] = []
+  -> print("someInts is of type [Int] with \(someInts.count) items.")
+  <- someInts is of type [Int] with 0 items.

+Alternatively, you can create an empty array of a certain type 
+using *initializer syntax*, 
+which is done by writing the type in square brackets 
+followed by parentheses (`[Element]()`):

-Note that the type of the `someInts` variable is inferred to be `[Int]`
-from the type of the initializer.
+Both approaches produce the same result. 
+However, the empty array literal (`[]`) is the preferred way to 
+initialize an empty array because it is more concise and aligns with 
+the style guidelines used throughout this guide.
