fix(symfony): reset the skolem IRI converter between requests (#8681)

SkolemIriConverter implements ResetInterface but its service was not tagged
kernel.reset, so in long-running workers (FrankenPHP worker mode) its object
map kept every object that received a genid IRI alive for the life of the
worker.
