Improve Documentation on how to persist aliases

In the docs https://www.nushell.sh/book/aliases.html there is this statement:

For more details about how to persist aliases so that they're visible when you start up Nushell, see the configuration chapter.

However, if you click on that configuration chapter link and then search the page, you only see a small confusing snippet of a nuopen override example for MacOS, and nowhere else does it show how to persist aliases.

echo $nu.scope.aliases does work to show current aliases made in a session, but there should be a way to persist them much more easily somehow?

Commencez par la page aliases.html et suivez son lien vers configuration.html. Comparez les instructions et les exemples existants concernant les alias persistants, puis mettez à jour la documentation afin qu’un lecteur puisse trouver les instructions pertinentes et vérifier que le lien mène à des informations utiles.
