[SPARK-31967][UI] Downgrade to vis.js 4.21.0 to fix Jobs UI loading t…

…ime regression

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

After apache#28192, the job list page becomes very slow.
For example, after the following operation, the UI loading can take >40 sec.
```
(1 to 1000).foreach(_ => sc.parallelize(1 to 10).collect)
```

This is caused by a  [performance issue of `vis-timeline`](visjs/vis-timeline#379). The serious issue affects both branch-3.0 and branch-2.4

I tried a different version 4.21.0 from https://cdnjs.com/libraries/vis
The infinite drawing issue seems also fixed if the zoom is disabled as default.

### Why are the changes needed?

Fix the serious perf issue in web UI by falling back vis-timeline-graph2d to an ealier version.

### Does this PR introduce _any_ user-facing change?

Yes, fix the UI perf regression

### How was this patch tested?

Manual test

Closes apache#28806 from gengliangwang/downgradeVis.
