Turbo: Can't add "pnp-vendorize" when I execute yarn install from project root

It looks like you're using Yarn 1.x which is far too old and did not yet have the Plug'n'Play API/install strategy; you need at least Yarn 3.x or newer. I should add that to the readme when I get a chance.

Check! I'm not familiar with Yarn as wel, but I found out that corepack prepare yarn@stable --activate upgraded to 4.x and now yarn install worked.

root@drplrefresh_drupal:/var/www# corepack prepare yarn@stable --activate
Preparing yarn@stable for immediate activation...
root@drplrefresh_drupal:/var/www# yarn --version
4.1.0
root@drplrefresh_drupal:/var/www# yarn install

Yup, that output looks correct to me, so you should have the Turbo library now sitting in the correct location. I actually had to do a similar thing to get modern Yarn working in GitLab CI for the project (see the .gitlab-ci.yml). I'll update the readme tomorrow to add this information.

I've added clearer requirements to the readme. Marking as fixed.
