Allow specifying locale for react/jsx-sort-props

[nizamiza]

We work in a team where people have systems with different locales. When we add react/jsx-sort-props to our eslint config, it behaves differently for each system.

For example, on a en-US system, props for the component below are sorted like this:

<RawFileField
  onChange={handleChange}
  onFileRemove={asMedia ? null : handleRemove}
  {...props}
/>

But on a sk-SK system, they're sorted like this:

<RawFileField
  onFileRemove={asMedia ? null : handleRemove}
  onChange={handleChange}
  {...props}
/>

This results in eslint tests passing locally, but failing during CI/CD pipelines. Ability to specify which locale to use for sorting would be nice.

That seems like a reasonable option - it would default to the current locale, and you could specify whatever value you wanted in the config.

Note that in node < 13, the sk-SK locale doesn't exist, so we should probably add some test cases for a locale that sorts differently than en-US, that's present in older versions of node.
