Docs feedback: Document the owner ID for AMIs

The instructions for installing in AWS specify that you search for an AMI matching a certain name: https://docs.gitlab.com/ee/install/aws/#choose-the-ami

This is open to abuse as anybody can publish an AMI under any name. Please include e.g. the owner ID in the query.

Also, it would appear that somewhere around Gitlab 11.11 you changed the owner ID for your AMIs from 855262394183 to 782774275127 and this doesn't appear to be documented anywhere.

How can I validate that e.g. ami-0626e44f0ff54d4d5 is produced by Gitlab and not some malicious actor?
