Fix the issue where the public dataset search result page displays public workflows after refreshing (#3230)

### Purpose:
Currently, after refreshing the public dataset search result page,
public workflow search results appear. The issue occurs because the URL
check and type update are only triggered when the `NavigationEnd` event
is detected. However, when the page is refreshed, it retains the default
type, which is the workflow search results.

### Changes:
Directly check the URL and update the type in OnInit.

### Demos:
Before:
before refreshing:
