Adding site

[TonioGela]

Addresses #5 (or at least it starts to :D)
@armanbilge I began adding the site structure but I don't have the rights to perform these actions 👇

- Grant "Read and write" permissions to workflows. 
- Set the GitHub pages source to the / (root) directory on the gh-pages branch.

Also the non-deprecated way of adding RelatedProjects seems to require both an import and a quite verbose syntax:

Verbosity here

import laika.helium.config._

// ....
.settings(
    tlSiteHelium ~= {
      _.site.mainNavigation(
        appendLinks = List(
          ThemeNavigationSection(
            "Related Projects",
            TextLink.external("https://github.com/typelevel/cats", "cats"),
            TextLink.external(
              "https://github.com/typelevel/cats-effect",
              "cats-effect"
            ),
            TextLink.external("https://github.com/typelevel/fs2", "fs2"),
            TextLink.external("https://github.com/http4s/http4s", "http4s"),
            TextLink.external("https://github.com/circe/circe", "circe"),
            TextLink.external("https://github.com/bkirwi/decline", "decline"),
            TextLink.external(
              "https://github.com/typelevel/munit-cats-effect",
              "munit-cats-effect"
            )
          )
        )
      )
    }
  )

is sbt-typelevel-site intended to be used that way? does a shortcut exist?

I can take care of it after the PR merges.

WDYT @armanbilge, are these examples enough to bootstrap the site? This will maybe raise some interest and people might contribute with their scripts in this way.
