[ResourceBundle] Improve redirection.

This PR contains two features

**Improve referer redirect with added `referer ` as key of redirect config**

 ```yaml
_sylius:
    redirect:
        referer: _referer # To set referer redirect by ?_referer=url_path
#or
        referer: true

#or
_sylius:
    redirect: referer
 ````

**Add `hash` key for redirect with hash**

```yaml
_sylius:
    redirect:
        route: ...
        parameters: ...
        hash: some_hash # This will redirect with url_path#some_hash
# or
_sylius:
    redirect:
        referer: true
        hash: some_hash # This will redirect with referer_url#some_hash
 ````
Instead you can use:
```php
if (!is_array($redirect) || empty($redirect['hash'])) {}
```
There is no need for the `null` check as you expect only `array`.
