Fix dismissal behavior of secret detection vulns

It seems that no vulnerabilities have the type `secret_scanning`
anymore, so the secret detection action was not being dispatched. This
meant that the real-time update of the vulnerability in the UI wasn't
happening, i.e., striking-through when dismissed, and removing the
strike-through when undoing the dismissal.
