Determine which of Issues API endpoints should be publish, and which should be private or experimental

[vartec]

As part of Improve APIs Initiative for each API endpoint and REST verb which currently don't have ApiPublishStatus set, we need to determine if it should be published as a public API, or marked as Private or Experimental.

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 current work is just creation of the these tickets, not actually publishing).

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.
