Transform regex with 'su' flag, using `dotAllFlag=false`

```
rewritePattern('hello.world', 'su', {
  dotAllFlag: false,
})
```

```
/hello.world/su.test('hello\nworld') 
// should output: true
```

```
/hello(?:[\0-\t\x0B\f\x0E-\u2027\u202A-\uD7FF\uE000-\uFFFF]|[\uD800-\uDBFF][\uDC00-\uDFFF]|[\uD800-\uDBFF](?![\uDC00-\uDFFF])|(?:[^\uD800-\uDBFF]|^)[\uDC00-\uDFFF])world/s.test('hello\nworld'))
// but output: false
```
