[ResourceItem] Fix broken focus ring styles (#10268)

### WHY are these changes introduced?

Resolves #10175.

Focus ring was broken on ResourceItem prior to uplift and was flagged
during se23 clean up.

### WHAT is this pull request doing?

Fixes minor issue on ResourceList.stories.tsx where LegacyCard was not
using the correct border radius on xs screens (should match IndexTable
where border-radius is set to `0` for xs screens).

Fixes focus ring styles by opting to use `offset` property as opposed to
the `focus-ring` mixin.
