Provide a seamless Github App installation experience about iambic

Could this potentially be an included command?? Such as plan.. maybe iambic integration

Then a it asks a series of questions, and provides an output file for Terraform and github, and if you expand you could just add other walk through options like using Azure automation for Azure users instead of Lambda..

Then it gives you the steps to apply the customized files to your github application??

Not exactly seamless, but could be an improvement.

I capture most of the required setting into the query params for new app creation

The docs now reference a link that includes most of the query params to create the App. Hopefully this makes installation simpler. It is not exactly seamless because we still need the user to update the org name.

Some future improvement can be incorporate the flow to the wizard, so we can dynamically generate the URI with the org name input by the user.
