Render should support plain text

[libasoles]

The render method accepts jsx, and something like text nodes, but plain text should be supported too. Otherwise it's neccesary to wrap text (or numbers) inside tags, like:

render(<>Hi</>, target);

And that's cumbersome.

See this working with React here:

Paste these lines:

import { render } from 'react-dom';

render("Hi", document.querySelector('#app'));
```javascript

Works with numbers too:

`render(55, document.querySelector('#app'));`
