Minor Documentation Issues

[AaronCoplan]

The new documentation system for the most part looks amazing and works well. However, I have had 2 minor issues with it.

1. Issue with the current page - could not resolve reference to Grid - I tried adding "./src/components/Grid/index.js" to the requires list in docs and rebuilding but could not fix it. (see fist attached screenshot for more info)

2. I tried building the docs for TabbedCard with the following code in TabbedCard.examples.md and got some errors that I believe are similar to the ones described in number 1. The code I tried is as follows:

<TabbedCard initialTab="Hello">
  <Tab title="Hello">Hello World</Tab>
  <Tab title="Goodbye">Goodbye</Tab>
  <Tab title="Complex">
    <Grid.Row cards deck>
      <Grid.Col md={4}>
        <Card body="Short content" />
      </Grid.Col>
      <Grid.Col md={4}>
        <Card
          body="Extra long content of card. Lorem ipsum dolor sit amet,
          consetetur sadipscing elitr"
        />
      </Grid.Col>
      <Grid.Col md={4}>
        <Card body="Short content" />
      </Grid.Col>
    </Grid.Row>
  </Tab>
</TabbedCard>
