Dashboard: remove option to manage recommended content

This seems to be a conceptional flaw of the dashboard refactoring.

Recommended content is not individually managed but by role.
Therefore, there is no way for a user to change that content.

@fhelfer FYI

@oliversamoila Thank you for your feedback.

This PR only targets the "multi manage" ability of recommended content, not the management in general.
This function was never implemented and therefore does not work. It just slipped in during the refactoring/streamlining of content blocks for ILIAS 9.

We may add this in future, but that should be within a feature request and not within a bugfix.

Greetings,

@oliversamoila Due to that clarification step, I would like you to give a conceptional approval as verification to my statement.

Alternatively, feel free to discuss any open points or suggest this to the JF.

Thanks @iszmais

I was reasonably sure that all the streamlining efforts in Global Dashboard Settings of Presentation and Sortation for all Dashboard Sections, Global Sorting for Dashboard Sections & KS-ViewControls for Dashboard Sections
also included this.

However, this is simply not explicit at all. I can certainly understand the view from this PR. No well-founded objections. 😉
