feat: Apps-2559 convert HeaderSticky to vue3

[farosFreed]

Connected to APPS-2559

Component Created: HeaderSticky.vue

Stories: ~/stories/HeaderSticky.stories.js

Spec: ~/stories/HeaderSticky.spec.js

Notes:

🍵 I don't entirely understand why the story for this component needs to parse the secondary data, but the component itself does not. For now I've kept it the same because this is how the component and story are implemented in Vue 2.

I looked in the Nuxt library to try to understand, and I see the menu is powered by this HeaderMainMenuItems graphQL query, but I don't know exactly what this returns on live.
