Add public datasets under "Hub" (#3129)

### Purpose:
Added a new interface for public datasets, allowing non-logged-in users
to view datasets shared by others. The behavior of public datasets
aligns with that of public workflows, ensuring consistent access and
interaction with public resources.

### Changes:
1. Added "Hub Dataset" to the left sidebar. Clicking on it will display
public datasets.
2. Updated the list item behavior: When a user clicks a list item of
type "dataset," different navigation actions are taken depending on the
situation:
- If the user is not logged in, they will always be redirected to the
Hub Dataset page. This page disables the download
functionality and does not display the publish switch.
- If the user is logged in but lacks direct access permissions (e.g.,
read or write), they will still be redirected to the Hub Dataset page.
- If the user is logged in and has read or write permissions, they will
be redirected to the User Dataset page, which is the original dataset
page we had.

### Demos:
**Before:**
