Move the folder structure for `admin jobs page` files

What does this MR do and why?

Moving the components folder for admin jobs page one level up in the folder structure for consistency, from app/assets/javascripts/pages/admin/jobs/index/components/ to app/assets/javascripts/pages/admin/jobs/components/.

I have oriented myself towards

/app/assets/javascripts/jobs/index.js and /app/assets/javascripts/jobs/components/
