chore(lib): update Switch

- In `src/components/switch/Switch.vue`,
    - `v-model` binding is updated for Vue 3,
        - `value` prop --> `modelValue`
        - `input` event --> `update:modelValue`
    - Setting a boolean attribute to `false` does not remove the
      attribute on Vue 3. It ended up with a grayed out switch.
      `disabled` should not directly be bound to the `disabled`
      attribute but a newly computed `disabledOrUndefined` has to be
      used instead.
    - Automatic ESLint fix is applied.
