Revisit Pipeline visibility details
## Issue
The changes add in https://gitlab.com/gitlab-org/gitlab/-/merge_requests/21297 are still not making this clear, and could even be wrong. We should double check everything and clarify it.
The initial research was tracked in https://gitlab.com/gitlab-org/gitlab/-/issues/25542#note_222947307, but I'm not convinced I got it all right and need to repeat it to make sure it's true.
The docs have been updated over time, and the key details are in https://docs.gitlab.com/ee/ci/pipelines/settings.html#change-which-users-can-view-your-pipelines, and probably should be double checked.
