[KYUUBI #5484] Remove legacy Web UI

### _Why are the changes needed?_

Close #5484

Kyuubi provides a basic new Web UI which is built on top of Vue3, we can remove the legacy dummy Web UI in 1.8.

The new UI hosts at `http://<host>:<port>/ui/` and the legacy UI hosts at `http://<host>:<port>/`, we should

1. Remove the legacy UI routing from Jetty
2. Remove all files related to legacy UI
3. Redirect `http://<host>:<port>/` to `http://<host>:<port>/ui/`

### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [x] Add screenshots for manual tests if appropriate

building with the command `build/dist --web-ui`, then `cd dist` and perform `bin/kyuubi run`

access http://0.0.0.0:10099 could correctly redirect to http://0.0.0.0:10099/ui/
