[Workplace Search] Remove unused components and redundant link (#112971)

* Remove user_icon and user_option_item components

They are no longer needed after the removal of Standard Auth

* Remove link wrapping image

It duplicates the link below the image and creates a redundant "external link" icon

* Fix typo
