refactor(reviews): refactor ReviewForm for more flexible rendering

[matthewvolk]

What/Why?

Refactors ReviewForm to accept a trigger prop (React.ReactNode) instead of formButtonLabel (string). This allows any React node as the trigger, not just a button with a label.

Changes:

• Removed formButtonLabel prop from ReviewForm
• Added required trigger prop (React.ReactNode)
• Moved button rendering to parent components (Reviews and ReviewsEmptyState), which create the Button and pass it as trigger

Improves flexibility and separation of concerns by letting parents control trigger rendering.

Testing

• Verified review form modal opens when clicking the trigger button
• Confirmed form submission works correctly
• Tested both empty state and non-empty state review sections
• Validated button styling and positioning remain consistent

Migration

Breaking change: ReviewForm no longer accepts formButtonLabel. Update usages:

Before:

<ReviewForm
  formButtonLabel="Write a review"
  // ... other props
/>

After:

<ReviewForm
  trigger={
    <Button className="mx-auto mt-8" size="small" variant="tertiary">
      Write a review
    </Button>
  }
  // ... other props
/>

The trigger prop accepts any React node, allowing custom trigger components.
