Subject: [PATCH] Fix PR file tree folders no longer collapsing (#22864)

Collapsing folders currently just throws a console error

```
index.js?v=1.19.0~dev-403-gb6b8feb3d:10 TypeError: this.$set is not a function
    at Proxy.handleClick (index.js?v=1.19.0~dev-403-gb6b8feb3d:58:7159)
    at index.js?v=1.19.0~dev-403-gb6b8feb3d:58:6466

    at ce (index.js?v=1.19.0~dev-403-gb6b8feb3d:10:1472)
    at Q (index.js?v=1.19.0~dev-403-gb6b8feb3d:10:1567)
    at HTMLDivElement.$e (index.js?v=1.19.0~dev-403-gb6b8feb3d:10:79198)
```

This PR fixes this and allows folders to be collapsed again.

Also:
- better cursor interaction with folders
- added some color to the diff detail stats
- remove green link color from all the file names
