add animations to changelog

+## [5.0.0-release-candidate-2]
+This version adds built-in support for animation in Flutter in an easy, clear way, and without having to create a StatefulWidget with controllers and animations. All you need to do is call the name of the animation.
+
+If you want to add a "fadeIn" effect to any widget, simply add .fadeIn() to the end of it.
+
+```dart
+ Container(
+              color: Colors.blue,
+              height: 100,
+              width: 100,
+       ).fadeIn(),
+```

+
+Maybe you want to merge two or more animations, just concatenate them at the end of the widget.
+
+```dart
+ Container(
+              color: Colors.blue,
+              height: 100,
+              width: 100,
+      ).fadeIn().bounce(begin: -0.8, end: 0.3),
+```
+

+
+
+Creating animation sequences in Flutter is one of the most painful things to do with the framework. You need to create tons of AnimationControllers. Well, using GetX 5 you just need to tell your animation that it is sequential. Just like that.
+
+```dart
+ const FlutterLogo(size: 110)
+                        .bounce(begin: -0.8, end: 0.4)
+                        .fadeIn()
+                        .spin(isSequential: true)
+                        .wobble(isSequential: true, begin: 0, end: 8)
+                        .flip(isSequential: true)
+                        .fadeOut(isSequential: true),
+```
+
+Result:
