patch

Removed the / prefix in the catalog SidebarItem element, as it is no longer needed.

To apply this change to an existing app, remove the / prefix from the catalog and any other sidebar items in packages/app/src/components/Root/Root.ts:

-<SidebarItem icon={HomeIcon} to="/catalog" text="Home" />
+<SidebarItem icon={HomeIcon} to="catalog" text="Home" />
