Enhance DialogData.js comments for expanded property getter and setter methods

[Copilot]

Description

Updated the JSDoc comments for the expanded property getter and setter methods in src/RoleObjects/DialogData.js to be more detailed and descriptive. The comments now span two lines each, providing better clarity and understanding for developers.

Changes

set expanded method comment

Before:

/**
 * Sets whether the element should get expanded
 * @access public
 * @param {boolean} val - true if expanded, false if not expanded, undefined if the field is unset
 */

After:

/**
 * Sets whether the dialog element is expanded or collapsed.
 * When expanded, the dialog's content is visible to the user.
 * @access public
 * @param {boolean} val - true if expanded, false if not expanded, undefined if the field is unset
 */

get expanded method comment

Before:

/**
 * Retrieves whether expanded
 * @access public
 * @returns {boolean} true if expanded, false if not expanded, undefined if the field is unset
 */

After:

/**
 * Retrieves whether the dialog element is expanded or collapsed.
 * Checks the 'aria-expanded' property in the underlying React props.
 * @access public
 * @returns {boolean} true if expanded, false if not expanded, undefined if the field is unset
 */

Impact

• No functional changes - Only documentation/comments were updated
• Improved developer experience - Comments now provide more context about what the methods do
• Consistent with codebase patterns - Follows the same style used in similar files like DocumentData.js and ComboBoxData.js

Testing

• ✅ All existing tests pass
• ✅ Linter checks pass
• ✅ Code formatting validated with Prettier

Original prompt

The file src/RoleObjects/DialogData.js in the repository nmahesh-cainc/createjs-accessibility contains comments for the set and get methods of the expanded property. These comments should be updated to make them more detailed and elaborated into two lines for better clarity and understanding. The changes should not affect the functionality of the code, only the comments.
