Move conditional expressions and ranges practice section

Conditional expressions and ranges practice, is only about conditional expressions, so it is better placed nearer to Conditional expressions.

Also, ranges is more suitable to be practiced with loops, so it would make more sense to group it with it, or to have its own practice section.

-Before talking about loops, it's useful to know how to construct ranges for loops to iterate over.
-
-The most common way to create a range in Kotlin is to use the `..` operator. For example, `1..4` is equivalent to `1, 2, 3, 4`.
-
-To declare a range that doesn't include the end value, use the `..<` operator. For example, `1..<4` is equivalent to `1, 2, 3`.
-
-To declare a range in reverse order, use `downTo.` For example, `4 downTo 1` is equivalent to `4, 3, 2, 1`.
-
-To declare a range that increments in a step that isn't 1, use `step` and your desired increment value.
-For example, `1..5 step 2` is equivalent to `1, 3, 5`.
-
-You can also do the same with `Char` ranges:
-
-* `'a'..'d'` is equivalent to `'a', 'b', 'c', 'd'`
-* `'z' downTo 's' step 2` is equivalent to `'z', 'x', 'v', 't'`

 ## Loops
 
 The two most common loop structures in programming are `for` and `while`. Use `for` to iterate over a range of
