New metadata field: update and revision

The last update and revision of a page can be displayed using synthetic metadata fields. This also makes it possible to display them in tables or filter them accordingly. For example, you can search for pages that have been changed by a specific person within the last 7 days. This supports an efficient search for pages and content.

To use the feature, a metadata field is added to the page, just like with other widgets.

The metadata field regarding update and revision always refers to the current page on which the field is added and displayed. In addition, in edit mode, the embedded metadata can be edited directly on the page.
