Add example subcommand

[sourishkrout]

Some idea what the command could be helpful with:

--> runme example
--> Display a list of supported languages
----> Go
---> Node.js
---> Python
---> etc
or scaffold by specific use case:
--> Terraform
--> Pulumi
---> Vercel

A very simple version could be to just open a browser with the examples section in the docs.
