Add Documentation for passing slots to child components

Hey i found this solution for passing slots to child components of a component. I think this should be in the official docu, because it's a cool trick and has a few usecases 😊

Code to pass on the $slots:

<template v-for="(index, name) in $slots" v-slot:[name]>
  <slot :name="name" />
</template>

Code to pass on the $scopedSlots require some more configuration, but it is similar to passing the $slots:

<template v-for="(index, name) in $scopedSlots" v-slot:[name]="data">
  <slot :name="name" v-bind="data"></slot>
</template>

By defining the templates like this in our parent component we passing on all the slots defined at the place where we use the parent component.

Start by reviewing the existing Vue documentation for slots and the linked source article. Document the demonstrated patterns for forwarding $slots and $scopedSlots, with the examples and use cases from the issue, and confirm the resulting guidance fits the project’s Vue 3 documentation.
