[23.1] Only show 'edit' on published pages when viewer is the owner.

[dannon]

Sharing pages doesn't grant edit permissions so I don't think we don't have to look at roles/etc. We'd generally prefer using encoded userId for comparison, but that's not available here for the page and actual security is enforced in the API, so this just displays (or not) the UI.

Following up in dev with an update to script setup+ts.
