improved redirect mapping (#2157)

In reference to issue: #1818 Redirect cases were only happening on the surface level, essentially just affecting the links on [blog index](https://alshedivat.github.io/al-folio/blog/page/4/index.htm) and [year tag](https://alshedivat.github.io/al-folio/blog/2022/). However, from the actual [site](https://alshedivat.github.io/al-folio/blog/2022/redirect/), it would automatically redirect to the `base_url` rather than the actual `redirect`. In my update, if `redirect: true`, like it is in `404.md`, redirect behavior is the same, redirecting to the `base_url`. If it is an external link, then the redirect is external. And finally if it is an internal redirect, like it is in https://alshedivat.github.io/al-folio/blog/2022/redirect/, than the redirect is `page.redirect | relative_url`
