docs: convert useListenFocusTriggers stories file to TS

[LoayTarek5]

Here are the main changes made to convert the code to TypeScript: Added type annotation for the text state: useState("-"). Specified the type for the ref: useRef<HTMLButtonElement>(null). Added type annotations for the event parameters in onFocusByMouse and onFocusByKeyboard: React.FocusEvent<HTMLButtonElement>. Added an empty interface RenderProps which can be extended later if needed. Added as const to the Overview object to ensure type inference for its properties. Resolves #2474
