Fix Image does not announce "disabled" (#31252)

Summary:
This issue fixes https://github.com/facebook/react-native/issues/30935 screenreader does not announce Image disabled accessibilityState.

As stated in AOSP View.java, the framework will handle routine focus movement, views indicate their willingness to take focus through the `isFocusable` method https://bit.ly/3dCnyHb

```
* <p>The framework will handle routine focus movement in response to user input. This includes
* changing the focus as views are removed or hidden, or as new views become available. Views
* indicate their willingness to take focus through the {link #isFocusable} method. To change
* whether a view can take focus, call {link #setFocusable(boolean)}.
```

The property is updated through its shadow node `ReactImageManager` method `setAccessible` https://bit.ly/3dDuK5L

```java
 * <p>Instances of this class receive property updates from JS via @{link UIManagerModule}.
 * Subclasses may use {link #updateShadowNode} to persist some of the updated fields in the node
 * instance that corresponds to a particular view type.
```
