Fix isAllowed of escapeStreamer (#22814) (#22837)
Backport #22814.

The use of `sort.Search` is wrong: The slice should be sorted, and
`return >= 0` doen't mean it exists, see the
[manual](https://pkg.go.dev/sort#Search).

Could be fixed like this if we really need it:

```

But I don't think so, a map is better to do it.
