feat(jsx): add @tiptap/jsx for more convenient rendering of Tiptap content

[nperez0111]

Changes Overview

This implements @tiptap/jsx which is a package that can render JSX in a node's renderHTML method to the format that Tiptap expects.
This makes for a more modern experience of describing the content of a Node as you might do in modern frameworks like React/Vue.

Implementation Approach

Here is an example of what this allows for:

/* @jsx jsxTiptap */
import { jsxTiptap, children } from "@tiptap/jsx";
import { Node } from "@tiptap/core";

const Nested = () => (
  <span>
    <span>{children}</span>
    <br />
    nested
  </span>
);

const Demo = Node.create({
  name: "demo",
  group: "block",
  content: "block*",
  draggable: true,
  addAttributes() {
    return {
      id: {
        default: null,
      },
    };
  },
  renderHTML({ HTMLAttributes }) {
    return <div {...HTMLAttributes}><Nested /></div>;
  },
  parseHTML() {
    console.log("parseHTML");
    return [
      {
        tag: "div",
      },
    ];
  },
});

export default Demo;

Testing Done

Need to add some tests for ensuring that the arrays are all generated correctly. More of a POC than anything.

I want to do this for v3, not relative to develop so I haven't worked on it in a minute

[bdbch]

Moved the target branch to next (we'll probably need to sync next with develop soon too)
