refactor(JSafeHtml): use createVNode

This allows us to directly insert the HTML without adding any extra DOM element

createVnode is internally used by createStaticVNode:

However, it requires a 2nd parameter, which is the number of nodes we want to insert,
which is unknown/not trivial to calculate at runtime.
According to the comment in the function, that's only needed for hydration (SSR),
so it should be safe for us as we're SPA only.

Here's a playground:
