fix: add VNode support to VueNode due to incompatible type

[ProgrammingWithSid]

Added VNode to the VueNode type definition to include virtual nodes returned by the h() function. This change addresses warnings related to bannerTitle and bannerIcon in the component. By including VNode in the type, we improve type safety and ensure proper rendering of icons when they are conditionally displayed.

const bannerTitle = props.title
  ? h(
    Text,
    { variant: 'headingSm', as: 'h2', breakWord: true },
    () => props.title,
  )
  : undefined;

const bannerIcon = !props.hideIcon
  ? h(
    'span',
    { class: styles[bannerColors.value.icon] },
    h(Icon, { source: props.icon || bannerAttributes[bannerTone.value].icon, }),
  )
  : undefined;
