Installation of aio-cli

Hi @varunmitra ,

I wonder, why you install aio-cli in such a complicated way like downloading the zip and building yourself, where a simple

>npm install -g @adobe/aio-cli

Suffices.. according to the documentation (https://github.com/adobe/aio-cli/blob/master/README.md)

Maybe we can fix that in future trainings? Would eliminate a couple of potential human errors in the trainings as well

Review the training materials and the aio-cli installation guidance in the README linked by the issue. Check where the zip-download and build instructions are given, then update the relevant training content to use the documented npm installation command and verify the resulting instructions are consistent.
