Breaking changes

If you are a host application developer, leveraging the following APIs for input validation scenarios, please note that breaking changes regarding the custom rendering of input elements and actions have been introduced in this version. All of the APIs that were modified were introduced in the 2.0.0 release:

| Old API | API in 2.3.0 | Notes |
| --- | --- | --- |
| `void registerInputHandler (IInputHandler, InternalId)` | `void registerInputHandler (IInputHandler, RenderArgs)` | **Scenario**: Custom rendering input elements. <br> **Change**: The use of InternalId was removed to avoid using the underlying C++ code. |
| `void setParentToCard (InternalId, InternalId)` | `void setParentToCard (long, long)` | **Scenario**: Custom rendering a hidden card. <br/> **Change**: The use of InternalId was removed to avoid using the underlying C++ code. |
| None | `void registerSubmitableAction (View renderedAction, RenderArgs)` | **Scenario**: Custom rendering an action that must trigger validation and input retrieval. <br/> **Change**: By adding this method, developers can now register custom actions to trigger input validation, this allows developers to avoid input validation in actions that don't require that process. |
| `boolean areInputsValid (SubmitAction)` | `boolean areInputsValid ()` | **Scenario**: Input retrieval <br/> **Change**: As actions now register their submit-like behavior, the reference to the action is not required to retrieve the last input validation result. This also avoids making additional validations to retrieve the last validation result. |
| `void setSelectAction (RenderedAdaptiveCard, BaseActionElement, View, ICardActionHandler)` | `void setSelectAction (RenderedAdaptiveCard, BaseActionElement, View, ICardActionHandler, RenderArgs)` | **Scenario**: Custom rendering containers with select actions. <br/> **Change**: A RenderArgs argument is added to be able to register submit actions for containers with select actions. |

New Features:
1. [Input Validation and Labels](https://github.com/microsoft/AdaptiveCards/issues/3081)
2. [Underline Support in TextRuns](https://github.com/microsoft/AdaptiveCards/issues/3051)
Breaking Changes:
1. This release introduces a change in the behavior of the interaction between Submit actions and ShowCard actions. Previously, all inputs in all parts of the card would be gathered when a submit action is pressed. Going forward, inputs will gathered only if they are on the same card as the Action.Submit, or on any parent cards of the card containing the Action.Submit in the case of a card under an Action.ShowCard. Inputs will **not** be submitted if they are on a card that is a child or sibling show card of the card containing the Action.Submit. This includes cards from Action.ShowCards in ActionSets in the body of that card. For more information see the input validation documentation [here](https://docs.microsoft.com/en-us/adaptive-cards/authoring-cards/input-validation#fields-to-be-validated-and-submitted).
2. [[.NET WPF] Input.ChoiceSet incorrectly defaults to "expanded"](https://github.com/microsoft/AdaptiveCards/issues/2446)
