Expand Shadcn Gallery to Showcase All Block

[jordanliu]

Currently, the Shadcn platform primarily highlights featured blocks, making it difficult to discover the full range of available designs. With so many valuable blocks already created, it would be great to have a dedicated gallery section that includes all blocks, not just featured ones. This would provide users with a comprehensive overview and make it easier to find and explore a wider variety of designs. The addition of search and filter options could further enhance the browsing experience, ensuring users can quickly find the blocks that best suit their needs.
