Make Ruby rundoc tutorial (more) dynamic and add .NET (#63)

* Update Rundoc version

* Simplify ruby RUNDOC.md

* Re-write Ruby docs to be dynamic

* Rename main markdown file

* Use 5006 for port

Same port as `heroku local`

* Update rundoc filename

* Update README now that Fir is announced

* Add a explanation to the docs folder

Includes information on how to build the docs.

* Add links to tutorials from README

* Re-order arguments

It's prettier

* Update to make slightly more dynamic

We still can't extract the article into it's own section, but this makes some progress.

* Remove "ruby" from shared docs

* Update rundoc version

* Add dotnet

* Ignore ruby getting started guide instead of deleting

* Update CI to add dotnet
