Fix store notice classes (#4568)

The `StoreNoticesContainer` component is using an incorrect class name for a "success" notice and also applying the general `woocommerce-message` (what's used by WC core for the "success" notice) to all notices. In some instances, this could cause the general `woocommerce-message` styles to be applied instead of the `woocommerce-error` or `woocommerce-info` styles.

This PR changes the use of `woocommerce-success` to `woocommerce-message` and prevents `woocommerce-message` from being applied to all notices.
