Boxed tabs background should extend to the full width of the content area

https://www.patternfly.org/components/tabs/html/#box

AAP uses the boxed tabs in the UI in pretty much all areas of AAP to show nested content. We'd like the background of the component to span full width to make the tab areas more distinct from the rest of the content background.

This is what it currently looks like (as also seen in the PF example above)

This is our desired state.

Making this change in the PF Component would help in avoiding the AAP UI team to do a workaround for this especially since it affects all areas in the UI.

Commencez par l’exemple de boxed tabs sur la page liée des onglets PatternFly et localisez l’implémentation correspondante du composant Tabs dans ce dépôt. Comparez les captures d’écran actuelles et souhaitées, puis vérifiez que l’arrière-plan de boxed tabs s’étend sur toute la largeur du contenu sans modifier les autres variantes d’onglets.
