Olivero: RSS feed block is not placed as per design on smaller screen.

Problem/Motivation

1. RSS feed block on the smaller screen is not placed as per design. The icon is placed on the right side and the text is placed on the left side in the Olivero theme but in design the placement is different. See in design, attaching design link here - https://www.figma.com/file/x5zBLbvoW1jsvyAOt4Gp9I/Olivero-Theme---Public...
2. The second issue is - the icon and text are not aligned, see screenshot2
3. Third issue is - Icon has border-radius in design but in Olivero theme radius is missing

Steps to reproduce

3. See the RSS feed block at the bottom
