Fix scroll-to-error hook null reference error

- Add null check in useScrollToErrorOnSubmit hook to prevent 'Cannot read properties of null (reading handleSubmit)' error
- Remove duplicate ScrollToErrorComponentExample component declaration
- Hook now gracefully handles cases where no form methods are available
- Adds warning message when form context is missing
