Improves on symfony#57541 to also allow numeric values `1` and `0` with `FILTER_BOOL => true`

Currently attempting to use the Serializer component to deserialize to deserialize a `1` or `0` result in the following error:
```
The type of the "booleanProperty" attribute for class "App\MyDTO" must be one of "bool" ("int" given).
```
