feat: Add support for space-y and space-x

[xiCO2k]

Hey,

This PR adds the support to the space-y and space-x utility class from tailwind: https://tailwindcss.com/docs/space

Example

render(<<<'HTML'
    <div class="my-1 mx-2 space-y-1">
        <div class="font-bold uppercase">Title</div>
        <div>Lorem ipsum dolor sit amet, consectetur adipisicing elit</div>
        <div class="text-gray">© 2022</div>
    </div>
HTML);

instead of:

render(<<<'HTML'
    <div class="my-1 mx-2">
        <div class="font-bold uppercase">Title</div>
        <div class="mt-1">Lorem ipsum dolor sit amet, consectetur adipisicing elit</div>
        <div class="mt-1 text-gray">© 2022</div>
    </div>
HTML);
