Add Heroku Scripts?

[whusterj]

Our Heroku Setup Guide has two shell scripts that would be a great addition to tn-cli OR to the bootstrapper itself.

The scripts:

• Create a new Heroku Pipeline with Apps
• Set Heroku env vars from .env file

For now I am prototyping this in my personal global justfile (~/.justfile).

It would be nice to decouple our Heroku setup from the bootstrapper. How and where we deploy I think could be a more proprietary secret sauce that we don't give away with the bootstrapper by default. It also opens the door for us to eventually support multiple deployment options (e.g. AWS directly) and choose a different one per project as we transition between preferred infrastructures.

TL/DR - I love the idea of doing a lot of this with tn-cli instead of putting it into the bootstrapper. SkipAlpha does this btw, but it's implementation isn't as stable or easy to upgrade as I'd like.
