Problem/Motivation
The Administer Nodes permission was renamed Administer Content, but "Role requires" text still refers to the former. Confusing.
These descriptions could also be worded better.
Proposed resolution
Change nodes to content for revert and delete descriptions (both all nodes - in the node.permissions.yml - and the dynamic permissions for different content types in NodePermissions.php). Make further changes for usability (see comments.)
Remaining tasks
UX review of changes desirable.
User interface changes
Descriptions in node section of /admin/people/permissions
API changes
None.
Data model changes
None.
