[SPARK-44857][CORE][UI] Fix getBaseURI error in Spark Worker LogPage UI buttons

### What changes were proposed in this pull request?

This PR aims to fix `getBaseURI` errors when we clicks Spark Worker LogPage UI buttons in Apache Spark 3.2.0+.

### Why are the changes needed?

Run a Spark job and open the Spark Worker UI, http://localhost:8081 .
```
$ sbin/start-master.sh
$ sbin/start-worker.sh spark://127.0.0.1:7077
$ bin/spark-shell --master spark://127.0.0.1:7077
```

Click `stderr` and `Load New` button. The button is out of order currently due to the following error because `getBaseURI` is defined in `utils.js`.
