Errata and showstoppers with Hello Magnolia

[william baker]

For devs following the tutorial, there are a few errata and a show stopper.

Errata in Hello Magnolia - Headless @ https://docs.magnolia-cms.com/headless/getting-started-with-magnolia-headless/hello-headless.html

* don't create and cd into basic-headless-demos.

* if you want to create a working directory, remove the ";" from the shell commands, and preferably don't create two directories with the same name since "git clone" will create the desired directory

* remove "hello-magnolia-headless" argument from the git clone command.  (Causes the git command to fail.)

Errata in Hello Magnolia - SPA @ https://docs.magnolia-cms.com/headless/getting-started-with-magnolia-headless/hello-spa.html

* don't create and cd into the minimal-headless-spa-demos directory....done by git

* "git clone" command here is GOOD!

Showstopper: In minimal-headless-spa-demos/spa/react-minimal, encountered the following:

    "Error:  error:0308010C:digital envelope routines:unsupported"

    More info can be found at stackoverflow questions/69692842

    * This error appears to be the result of SSL3.0 and recent versions of node.  In particular, node 17+ is documented, but I am failing with node 16.14.0.

    * Suggested solution of setting NODE_OPTIONS fails (not allowed in 16.14.0)

    * .npm solution will not work for this project config.
