fix: incorrect jsx attribute name AST

[chenxsan]

I just noticed that ESLint failed to lint mdx now with the latest eslint-plugin-react here webpack/webpack.js.org#6377.

Here's an example mdx file:

---
title: hello
---

<div className='hi'>hello</div>

Here's the ast eslint-plugin-react would print for <div className='hi'>hello</div> node (https://github.com/jsx-eslint/eslint-plugin-react/blob/64ad60299d8c7d7534785c455694291b4c7aa427/lib/rules/no-unknown-property.js#L517):

<ref *1> {
  start: 27,
  end: 36,
  loc: {
    start: { line: 5, column: 5, offset: 27 },
    end: { line: 5, column: 14, offset: 36 }
  },
  range: [ 27, 36 ],
  raw: 'className',
  type: 'JSXAttribute',
  name: {
    start: 27,
    end: 41,
    loc: { start: [Object], end: [Object] },
    range: [ 27, 41 ],
    raw: "className='hi'",
    type: 'JSXIdentifier',
    name: 'className',
    parent: [Circular *1]
  },
  value: {
    start: 37,
    end: 41,
    loc: { start: [Object], end: [Object] },
    range: [ 37, 41 ],
    raw: "'hi'",
    type: 'Literal',
    value: 'hi',
    parent: [Circular *1]
  },
  parent: <ref *2> {
    type: 'JSXOpeningElement',
    name: {
      start: 23,
      end: 26,
      loc: [Object],
      range: [Array],
      raw: 'div',
      type: 'JSXIdentifier',
      name: 'div',
      parent: [Circular *2]
    },
    attributes: [ [Circular *1] ],
    selfClosing: false,
    start: 22,
    end: 42,
    loc: { start: [Object], end: [Object] },
    range: [ 22, 42 ],
    raw: "<div className='hi'>",
    parent: {
      start: 22,
      end: 53,
      loc: [Object],
      range: [Array],
      raw: "<div className='hi'>hello</div>",
      type: 'JSXElement',
      openingElement: [Circular *2],
      closingElement: [Object],
      children: [],
      parent: [Object]
    }
  }
}

The name part doesn't seem right to me, and it's causing an error:

$ npx eslint ./src/test.mdx
/Users/sam/Documents/githubRepos/webpack.js.org/src/test.mdx
  5:6  error  Unknown property 'className='hi'' found  react/no-unknown-property

✖ 1 problem (1 error, 0 warnings)

Actually I believe it's not really an issue in eslint-plugin-react, more like a bug in eslint-mdx parser which gets exposed by eslint-plugin-react's recent change. But I could be wrong since it's beyond my expertise :)

I'll do some investigation ASAP. ESLint compatible AST could really be different with the acorn's.
