Implementation details

1. Move the existing implementation to the Wildcard package.
2. Extract styles required for the component from Bootstrap to a CSS module:
   • Extract classes from node_modules/bootstrap/scss/_tooltip.scss into a component CSS module.
   • Merge our tooltip global styles with the newly created CSS module.
   • Merge our tooltip SCSS variables with the newly created CSS module.
   • Feed CSS module classes to the Reactstrap Tooltip implementation to avoid relying on the global .tooltip class.
3. Move client/branded/src/components/tooltip/Tooltip.story.tsx (link) to the new component folder and update it to match other stories in the Wildcard package.
4. Use the <button> component as a blueprint for the new component.
