add options for contributing

[ungoldman]

Contributing needs to be a list rather than an input.

Currently it's just Open-2. I don't know of many templates for Contribution Guidelines other than https://github.com/jden/CONTRIBUTING.md. Would be nice to have some options. At the very least:

• Open-2
• None

@jden would you say https://github.com/jden/CONTRIBUTING.md has any kind of name in terms of what sort of contributing document it is? My impulse is to call it "Inclusive".

I like the name "Inclusive" for https://github.com/jden/CONTRIBUTING.md . It targets the non-directly-code-related aspects of contribution guidelines, and is modeled after rust. It aims to give guidance on social aspects of project development, articulate the particular kinds of contributions the project is looking for (eg an "onramp" for new contributors) and to clarify project channels of communication.

It is modeled after the rust CONTRIBUTING.md

@jden thanks! 👍

going with just a (y/n) default boilerplate that blends elements from "open open" and https://github.com/jden/CONTRIBUTING.md since neither cover exactly what I was going for. good stuff all around 👍
