fix(AlertBadge): return type (#1881)

## 📝 Changes

- Fixes the return type in `AlertBadge` causing type errors in consumers
with the added React 19 support

> In React 19, ReactNode was expanded to include bigint and
Promise<AwaitedReactNode>. When a component returns children (typed as
ReactNode) directly, TypeScript sees the return type as the full
ReactNode union, which includes types that aren't assignable to what JSX
expressions expect from a component. The consumer's React 18 types don't
understand Promise or bigint as valid JSX return types, causing the
mismatch.
