The SVG icon on the actions dropdown for activities should not be visible to screenreaders

Problem/Motivation

The dropdown button that contains links like "Edit", "Delete" and "Report" that's available on activities and other content contains an arrow SVG that is decorative. The aria-label already tells screenreaders what they need to know so the SVG icon should not be visible to screen readers.

Proposed resolution

Mark the mentioned SVG element as decorative by hiding it from screenreaders.

Remaining tasks

• Identify and list the places where this component is used or if it's a shared implementation, where that implementation is
• Ensure the SVG icon itself is not seen by screenreaders in links.html.twig in socialbase

User interface changes

The SVG will no longer be visible for screen readers, leaving only the "More options" label. No visual changes.
