Baseweb: [Card] Expose `srcset` attribute for <HeaderImage /> in <Card />

[jonsadka]

Feature description

In addition to the src attribute on the <Card /> component, it would be helpful to pass an optional srcset attribute (mdn). For example

<Card
  srcset={'https://source.unsplash.com/user/erondu/700x400 w400, https://source.unsplash.com/user/erondu/700x1200 w1200'}
  headerImage={'https://source.unsplash.com/user/erondu/700x400'}
>
  Contents
</Card>
