Some advice for improving the explore projects page

[Reeleon]

Advices for explore projects page:

1. Open a project in a new window instead of the current window.
2. Add more filters, such as Language model tasks/multimodal model tasks......
3. Filter projects by tasks, systems, users. By advanced search, or a optional list. For example, if I choose GPT-4, I will get all projects whose system list contains GPT-4.
4. A whole view of the hub, such as the total number of the projects.
5. Optional layout methods. Project card as current, or list the project just like the windows file system could do.
6. The search function has something wrong. When I try to search xxx several times, sometimes it comes out no projects (there should be no projects indeed), sometimes it comes out with irrelevant projects.
