[Schema Inaccuracy] alert field of secret scanning alert webhook events have no required fields

[ebickle]

Schema Inaccuracy

The secret-scanning-alert-webhook schema component, used by the alert field of the webhook-secret-scanning-alert-* webhooks (e.g. webhook-secret-scanning-alert-created, does not have any required fields.

The alert is the subject of the webhook and is never optional. Many of the fields of the alert are primary keys or other required elements, such as number, created_at, updated_at, url, html_url, and many more.

Expected

The alert field of all of the webhook-secret-scanning-alert- webhooks should have required properties.

Reproduction Steps

Discovered by using TypeScript and reviewing the code of the ghec REST API descriptions. Using code, it can be discovered by:

import { webhooks } from '@octokit/openapi-webhooks-types-ghec'

type SecretScanningAlertCreatedEvent = webhooks['secret-scanning-alert-created']['post']['requestBody']['content']['application/json'];

const event: SecretScanningAlertCreatedEvent;
// Review type of event - all fields have a type that includes `| undefined`
