fix: Improve External Link Security - Meeds-io/MIPs#159

Prior to this change, the target external link of sidebar items was all time 'NEW TAB Strategy' and without a 'rel' attribute. This change will fix the behavior of 'External Link Target' in addition to the Security fix of missing 'rel' attribute.
