Rather than constantly linking our docs to meta-ts, import the
documentation directly into our tree and switch all the external links to
internal ones.

Note that there are still some links pointing to older ledge-rp images,
because we don't have a stable snapshots directory yet.
Those will be fixed once the gitlab build stabilizes
