[BUG] New dcc.Markdown does not render markdown tables

[AnnMarieW]

@KoolADE85 This is a breaking change from the update in #3960

As of react-markdown v5, the remark-gfm plugin is required to render tables

After the changes, this example:

dcc.Markdown(
    """
    # Products            
    
    | Product | Category | Price |
    | --- | --- | --- |
    | Apple | Fruit | $1.50 |
    | Broccoli | Vegetable | $2.25 |
    | Milk | Dairy | $3.50 |           
    
    """
),

renders like this:

---

---

This is from the react-markdown README

Here is an example that shows how to use a plugin (remark-gfm, which adds support for footnotes, strikethrough, tables, tasklists and URLs directly):

import React from 'react'
import {createRoot} from 'react-dom/client'
import Markdown from 'react-markdown'
import remarkGfm from 'remark-gfm'

const markdown = `Just a link: www.nasa.gov.`

createRoot(document.body).render(
  <Markdown remarkPlugins={[remarkGfm]}>{markdown}</Markdown>
)
