(DOCS) Document fix to int() function.

In #438 we changed the `int()` function to error on input that
isn't a string or an integer to align with the behavior of the
ARM template function.

This change:

- Updates the documentation for the function to match the updated
  behavior and removing the note about the now-patched bug.
- Adds an entry for the fix to the changelog.

+- Fixed the behavior of the [int()][int()] configuration function to error when given an input
+  value other than a string or integer. Prior to this release, when you specified a number with
+  a fractional part as input for the function, it coerced the input value to an integer representing
+  the fractional part. Starting with this release, the `int()` function raises an invalid input
+  error when the input value isn't a string or an integer.
