Use `shallowRef` instead of `ref` in `.vue` files where possible (#34813)

This PR improves some `.vue` components by using `shallowRef instead of
ref`, which `should improve performance`. It's probably not significant,
but it's an improvement because Vue no longer deep watches the ref
(shallowRef). Also i used `useTemplateRef` instead of `ref`.
