bug(linter) bug in fixer for `no-hex-escape`

```
bunx oxlint@latest -D all -D no-hex-escape --fix <file name>
```


input:
```ts
const unicodeMatch = "".toString().match(/[^\x00-\xFF]+/g);
```

actual fix:
```ts
const unicodeMatch = "".toString().match(/[^\u0000-\u00FF]+//);
```


expected fix: (i think)
```ts
const unicodeMatch = "".toString().match(/[^\u0000-\u00FF]+/g);
```
