Fix ModelAlerts view stories

[charisk]

The ModelAlerts view won't return any HTML if the variantAnalysis isn't set, so I've updated the component to be able to receive that, along with repo states and repo results, through props. We follow this pattern elsewhere.

Was this noticeable in the extension itself? Your changes are in the general ModelAlerts view, did we have a bug?

No there's no bug (also reminder that this view is for a prototype, not a released thing, so it probably has lots of "bugs" 😬 ).

It's just that the component returns empty HTML if variant analysis isn't set so the story is kind of pointless without it.

The changes to the view make it possible to make it easily "storyable".
