Fix rule media-feature-range-notation to use 'prefix' notation

[colinrotherham]

A previous update to Stylelint included the rule media-feature-range-notation

But similar to other rules it enforces syntax that is incompatible with Internet Explorer

This PR changes the default to context prefix until Media Queries Level 4 range context is better supported

.govuk-footer__copyright-logo {
  background-image: govuk-image-url("govuk-crest.png");

- @media (resolution >= 2dppx) {
+ @media (min-resolution: 2dppx) {
    background-image: govuk-image-url("govuk-crest-2x.png");
  }
}

Note: Autoprefixer only handles prefixes but a PostCSS plugin for @media range context is available

Sneaky, thanks for spotting it. Looks like we'll need to keep a keen eye on Stylelint's changelog in regards to IE11 compatibility for now 😔

I'd be keen to make that PR bump the versions to 1.1.1 so a patch release gets published as well 😊

Thanks @romaricpascal

Sounds good, I'll update the version number then merge
