…1616) ## Description Updated ScrollView Animation sample to display C# code, include default, accordion, and teleportation animations, and fixed code visibility handling to prevent overlap. With dynamically updated animation duration in the code displayed, main changes are: - **Added Sample Code Files**: - Included three new sample code files for different scroll animations: - `ScrollViewSample3_DefaultAnimation_cs.txt` - `ScrollViewSample3_AccordionAnimation_cs.txt` - `ScrollViewSample3_TeleportationAnimation_cs.txt` - **Updated Sample Code for Scroll Animations**: - Provided sample code for three types of animations (Default, Accordion, Teleportation) to be used in the `ScrollView_ScrollAnimationStarting` method. - **Updated Sample Code for Animation Duration Handling**: - Implemented dynamic updating to ensure that the animation duration is reflected in the displayed sample code when the value changes. - **Updated `ReevaluateVisibility` Method**: - Modified the `ReevaluateVisibility` method in `SampleCodePresenter` to only collapse the visibility when the content is empty. Leave the updated method visibility management to `HandlePresenterVisibility()` only in `ControlExample` to prevent overlap of XAML and C# code. ## Motivation and Context By adding and updating sample code for different scroll animations (default, accordion, and teleportation), users can better understand and implement various animation styles in their ScrollView components. It is also fixing this issue: #1603 ## How Has This Been Tested? The changes were **manually tested** by verifying that the correct sample code is displayed for different animations, ensuring dynamic updates to the animation duration in the displayed example code, and confirming that the code presenter visibility is correctly managed. ## Screenshots:    ## Types of changes <!--- What types of changes does your code introduce?
