Remove single_line_throw rule

[samuelmaudo]

The Symfony rule set includes a rule to force throwing exceptions on a single line.

This means that some like this:

throw new BookingDocumentSlotAlreadyCreated(
    $bookingId,
    BookingDocumentType::passport(),
);

Becomes this:

throw new BookingDocumentSlotAlreadyCreated($bookingId, BookingDocumentType::passport());

This PR proposes to skip that rule, since it is sometimes easier to read the code if we to spread the class construction over several lines, specially when the constructor has several parameters.
