Review TeamAlerts endpoints to publish or make private

[vartec]

API endpoint to review:

• TeamAlertsTriggeredIndexEndpoint::GET
• TeamAlertsTriggeredTotalsEndpoint::GET

Documentation on determining if API should or shouldn't be public and how to publish: https://develop.sentry.dev/api/public/

If an endpoint is determined as a candidate to be published, create an issue and link it in this placeholder epic

Note: scope of this ticket is only to either create ticket for publishing, or marking private/experimental.

If endpoint is determined to be kept private or experimental, it should be marked as such with ApiPublishStatus. Example:

sentry/src/sentry/api/endpoints/user_notification_email.py

Lines 19 to 24 in dc65f98

	class UserNotificationEmailEndpoint(UserEndpoint):
	publish_status = {
	"GET": ApiPublishStatus.PRIVATE,
	"PUT": ApiPublishStatus.PRIVATE,
	}
	owner = ApiOwner.ISSUES

This a minimal change, so no point in creating a separate ticket.
