[Feature]: Support webcomponent

[dennyak47]

What problem does this feature solve?

Support webcomponent, so the story render function can support:

import {html} from "lit"
const primary = {
  render:()=>html`<my-component></my-component>`
}

What does the proposed API look like?

import {html} from "lit"
const primary = {
  render:()=>html`<my-component></my-component>`
}
