Fix the following issue in Symfony AI profiler view which appears when using `blog` demo which has a `clock` tool returning a `DatePoint` instance:

```
An exception has been thrown during the rendering of a template ("nl2br(): Argument #1 ($string) must be of type string, Symfony\Component\Clock\DatePoint given") in `@AI`/data_collector.html.twig at line 242
```
