Widgets: Match variable types in rss feed link filter.

Browse Source 
The `rss_widget_feed_link` filter added in [52031] documents the parameter as a string, but recommends removing by returning false. Change the recommendation and documentation to make this consistent and update Twenty Twenty One to use the new recommended return value. Maintains documentation as possibly returning `false` for backwards compatibility.

Props sabernhardt, Mista-Flo.
