Add a preferred node version

[luischoma]

Hey!!

First of, thanks for the great and very useful initiative!

I would like to suggest adding a .nvmrc file to the project. The reason is that, on my case, I have an older node version installed and used by default. When trying to run the first exercise I would get this error:

  argv.passWithNoTests ?? (argv.passWithNoTests = true);
                        ^
SyntaxError: Unexpected token '?'

This is related to vite configs I guess, but since installing dependencies didn't throw any error took me a few minutes to realize it was the node version. Adding the preferred node version to the project would help to identify this earlier.

I believe all currently supported versions of Node should work, but considering that the installed version of @types/node is ^18.6.5 the recommended Node version to use would be 18.x

Hey! I think an LTS version of Node is a safe assumption for a project to make without needing to do anything our side.
