Update icon shown for world_readable rooms (#6111)

* Update icon shown for world_readable rooms

Followup to #6090: having discussed this in the team, we want to show a
different icon (with different text) for rooms where the history_visibility is
`world_readable` rather than `shared`.

* delint

* Update screenshots
