Remove whitespace in Markdown

[MBurchard]

Hi @antfu,

Thank you very much for this project, it offers a lot of useful defaults and has made my old ESLint configurations almost completely superfluous.
That's the rest of the customisations I use.

import antfu from '@antfu/eslint-config';

export default antfu({
  ignores: [
    '*.svg',
  ],
  stylistic: {
    semi: true,
  },
}, {
  rules: {
    'curly': 'off',
    'regexp/strict': 'off',
    'style/brace-style': ['error', '1tbs'],
    'style/max-len': ['warn', {code: 120}],
    'style/object-curly-spacing': ['error', 'never'],
    'style/operator-linebreak': ['error', 'after'],
  },
}, {
  files: ['**/*.md'],
  rules: {
    'no-trailing-spaces': 'off',
    'style/max-len': 'off',
  },
});

ESLint always removes the two spaces at the end of lines that are used to create a line break in MD files.
I've tried 'no-trailing-spaces': 'off', but that obviously didn't do it.
How can I fix it?
Would this fix be something for everyone and should be standard for MD files?

It's [style/no-trailing-spaces](https://eslint.style/rules/js/no-trailing-spaces)

I agree that it should be disabled for Markdown though
