message: refactor(docs-infra): scope footer styles to the `<aio-footer>` element
  This commit ensures that all styles for the page footer (which are
  defined in `_footer.scss`) only apply to elements inside an
  `<aio-footer>` element. This will prevent the styles accidentally taking
  effect on a different part of the app.
