Card: Add a border design token

[BenJackGill]

Describe the bug

The Card element has a card.border.radius design token.

But it impossible to set card.border design token preset.

This is very strange since the home page shows the Aura theme Cards that have a flat border. In reality, those Card elements have a shadow and no border is able to be set.

To make something that looks like the homepage we need to do something like this, which is only partially possible without the card.border design token:

import { definePreset } from '@primeuix/themes';
import Aura from '@primeuix/themes/aura';

export const preset = definePreset(Aura, {
  components: {
    card: {
      root: {
        border: 'border-surface border', // This does not work because there is no `border` token
        shadow: 'none', // This works, it removes the shadow
      },
    },
  },
});

This is very strange since the home page shows the Aura theme cards that have a flat border. In reality, those Card elements have a shadow and no border is able to be set.

If you have a look at the code for the Overview example, it doesn't use PrimeVue cards.

Yeah thats what I mean, the home page has something else used in place of what looks like a Card component. Then the real Card component has a shadow and no border. I can almost recreate the home page "fake card" look used on the homepage by removing the shadow but I can't easily add a border. That is why I was asking for a border design token.

The home page not using a real Card component is not really the problem, I just think the Card component could really do with a border token that can be styled by us. Seems like a basic thing for that component to have style wise.

Especially since it already has card.border.radius but no possible card.border.
