fix: use absolute path in cookie_consent.html (#2804)

Adding `site.GetPage /privacy.md` to reflect the absolute path to `privacy.md`, as per the Hugo documentation for GetPage.

This should force Hugo to only link to a `/privacy.md` page at the root of the site and prevent Hugo searching for unrelated pages with `privacy` in the name (as it currently does, if for example you also have a /tags/privacy/ page).

Note that currently there's a Hugo bug where Hugo does not respect absolute paths in `site.GetPage`. Hence, Hugo can still return other unrelated pages (for example any other pages that have `privacy....` in the filename) until this bug is fixed: https://github.com/gohugoio/hugo/issues/10243
