Enable quarantined service ping metrics

At https://gitlab.com/gitlab-org/gitlab/-/merge_requests/71722
secure product type metrics was put into quarantine due to performance
issues. Underlying index problem was resolved by
https://gitlab.com/gitlab-org/gitlab/-/issues/343455 and
service ping report was successfully generated for gitlab.com.
There is no more a need to keep this metrics in quarantine.
Therefore corresponding feaure flag is removed.
