Updated the store listings page

I updated Zindies' store listings page. Like the events list, stores can now be displayed by region. There are still relatively few listings, and I feel bad that we haven't been able to introduce the creators who have registered yet, but I added a banner on each page asking shops to share their information. The banner is placed at the end of the store list and is more prominent in areas with fewer listings. I'd be grateful if anyone who sees this could provide information. Please do. 🙏
