Add async to render() function of Block Editor Components

[moomoo-dev]

Describe a bug.

I'm trying to render HTML from MathJAX, and it requires an await.
The problem is the render function doesn't allow Promise functions because every time I try it tells me it can't append node.

Is there a reason that this isn't allowed? I really have no other way to render this data otherwise

Editor.js version: 2.31.1

Plugins you use with their versions:

I can also help with this pull request if possible.

I'm looking at the code and in tools/stub/index.ts

I would I need to make this function a promise?
/**

• Returns stub holder
• @returns {HTMLElement}
  */
  public render(): HTMLElement {
  return this.wrapper;
  }

Also I plan on being a big contributor of code. I want to use this editor for a e-commerce app I want to make. So this app is sort of a priority for me.

You can use prepare() static method to do asynchronous job.

Let me know if it is still actual.
