Recommended config

Add recommended configuration by adding the following to extends in your stylelint configuration:

@double-great/stylelint-a11y/recommended

This shareable config contains the following:

{
  "plugins": ["@double-great/stylelint-a11y"],
  "rules": {
    "a11y/media-prefers-reduced-motion": true,
    "a11y/no-outline-none": true,
    "a11y/selector-pseudo-class-focus": true
  }
}

Since it adds stylelint-a11y to plugins, you don't have to do this yourself when extending this config.
