Amended reporters to no longer throw non-scalar value within symfony6

[Wordlesschunk]

Currently when trying to add a reporter within the config in symfony6 I was dealt with the error 'Input value "reporters" contains a non-scalar value.'
I found that changing
$reporters = $request->query->get('reporters') ?? [];
to
$reporters = $request->query->all('reporters') ?? [];
resolved this issue.
