 * This hook is used to manage the state of the attachment picker bottom sheet.

 * The bottom sheet is used to display the attachment picker UI.
 * The `openPicker` function opens the bottom sheet, and the `closePicker` function closes it.
 * The `bottomSheetRef` is a reference to the bottom sheet component, which allows for programmatic control of the bottom sheet.
