CE-1941: fix error boundary reload button

When clicking the "Go to home" button on the errorboundary page, navigation doesn't occur as expected. This is because the boundary reset function wasn't being passed into the button.

Now when you test the ErrorBoundary page, clicking the return to home button should cause ... inception (storybook rendered inside storybook). This means it is working as expected now!

I've also created a second story to demonstrate the customization required on the ErrorPage shared component. (just a demonstration)
