Document attachments endpoint APIs

[abiewer-bb]

Problem Statement

Please document the following APIs for general consumption (unless I missed it in the docs, in which case please point me to the correct location). I know they exist and would love the assurance that they will be maintained so I can incorporate them into my application.

https://sentry.io/api/0/projects/{org}/{project}/events/{eventId}/attachments/, and
https://sentry.io/api/0/projects/{org}/{project}/events/{eventId}/attachments/{attachmentId}/?download=1

I do not have rights to add the "Component: API" label to the issue. Please do not close this!
