This change makes the following updates to the UX of the taxonomy pages: * On the taxonomies list, display the full name of taxonomies in a tooltip if it's longer than what's displayed * On the taxonomy detail page, please change the title of the "Value" column to "Tag name" * On taxonomy detail page, remove the "child tags" column and put it in parentheses instead * Update tags count color * Several minor issues brought up here: https://github.com/openedx/modular-learning/issues/105#issuecomment-1829412705. * Fix issue with scroll position not being reset on navigation
