Subject: [PATCH] Update onFocusChanged in SelectableLazyColumn (#372)

The onFocusChanged function in SelectableLazyColumn has been updated to trigger onSelectFirstItem if the component receives focus and no items are currently active or selected. This ensures an item gets automatically selected in absence of any selected or active items, improving user experience and interaction flow.
