feat(PageReference): Public page reference lookups

Allow to resolve page references by share token to support lookups from public shares. This adds link previews for links to other pages in the same collective in public shares. It requires the new public reference API from nextcloud/server#46378 and the Text app being built with nextcloud-libraries/nextcloud-vue#5800. Fixes: #1275 Contributes to nextcloud/text#5520 Signed-off-by: Jonas <jonas@freesources.org>
