Description

There seem to be copy/paste error. The link for the "Concepts" was actually directing to the "Tutorials" section

Updated the reference to concepts and tested locally.

I would also add that the links do not work on the Codespace, but do work Locally.

When starting server on code space, the docs will be at a url such as
https://effective-space-computing-machine-q966j4q5x6c9wrx-1313.app.github.dev/

Clinking a reference attempts to direct to http://localhost:1313/tutorials/ but that doesn't exist.

There is probably a way to configure Hugo to use absolute urls and supply the base as environment variable when setting up the container / code space, but that would be out of scope.
