fix: hydration __vnode missing

[antfu]

In the basic renderer, we inject __vnode on dev for devtools to grab it. We missing that information in SSR as we didn't do so in hydration.

core/packages/runtime-core/src/renderer.ts

Lines 689 to 698 in a6ae876

	if (__DEV__ || __FEATURE_PROD_DEVTOOLS__) {
	Object.defineProperty(el, '__vnode', {
	value: vnode,
	enumerable: false
	})
	Object.defineProperty(el, '__vueParentComponent', {
	value: parentComponent,
	enumerable: false
	})
	}

@antfu can you add a test pls

I'd love to, but we didn't even have any tests for devtools. It might be better to delegate that to another PR.
