Dismiss button for "folder content best viewed in collectives app" header in file list

Browsing a folder which belongs to a collective in the files app shows a message "The content of this folder is best viewed in the Collectives app." on top of the file list.

Allow to dismiss the info header in the file list. It should be a persistent change for the user.

Background

For our use case most content (e.g. the files displayed in that folder) is currently not displayed from within the collectives app.

I assume this message is intended for users that only (automatically) store the collective "wiki style" markdown pages in the folder hierarchy below Collectives/collective_name.

However the automatically created folder Collectives/collective_name can be used for normal "file sharing" within the collective as well - and in that case, above message doesn't make much sense - as here, the content of this folder is not best viewed in the Collectives app, because it doesn't display relevant parts of the folder.

Start by locating the file-list UI that renders the “The content of this folder is best viewed in the Collectives app.” header for folders under Collectives. Trace how user-specific preferences are persisted, then verify that dismissing the header hides it for that user on subsequent visits while leaving other users unaffected.
