v7.0.0

Changed

• Updated stylelint peerDependency range from ^10.0.1 || ^11.0.0 || ^12.0.0 to ^13.0.0

Node.js v10 or newer is required. That's because stylelint v13 itself doesn't support Node.js versions below 10.

• Bumped up stylelint-order dependency to ^4.0.0
• Update test expectations to not require specific error message order
