feat: Add sorting list options for secret scanning

[maaarcelino]

Similar to #3477 this adds the missing sorting options from the SecretScanningAlertListOptions struct.

These options are available in the list-secret-scanning-alerts-for-a-repository endpoint and the respective ones for orgs and enterprises.
