expand headers type in DataTableSkeleton, fix DataTableRow type to require "id"

[metonym]

Features

• Expand headers prop type in DataTableSkeleton to be consistent with that of the DataTable (issue DataTable Skeleton - headers prop #413)

This enables you to share headers between the DataTable and DataTableSkeleton components:

{#if loading}
  <DataTableSkeleton {headers} />
{:else}
  <DataTable {headers} {rows} />
{/if}

Fixes

• Update DataTableRow prop type in DataTable to require an "id" key and value (issue Datatable - Sortable - Bug or better documentation? #414)

Documentation

• Add example "Skeleton with object headers" to DataTable docs
• Document that the DataTable is keyed ("key" for headers, "id" for `rows)
