jdlrobson 3ed167f318 [storybook] Document button usage and update broken stories
* add stories for buttons and icons using wvui and mwui
* Update user link stories
* Add the vector-menu-dropdown-noicon class to more and
variants menu
* Fixes the language button story and simplifies its code.
* Updates Hooks::makeButtonIcon to Hooks::makeIcon which
reflects the method purpose more. It doesn't output button
classes.

Bug: T289514
