Recognize all contributors to the InnerSource Patterns

It would be nice to recognize all contributors to our InnerSource Patterns in a public way.

A couple of ideas why that might be useful:

• people that have committed code to this repo are already visible here however that is a bit hidden
• there might be contributors that have helped in ways other than sending pull requests

Some tools I found:

• There is the allcontributors.org project that offers a way to recognize all contributors and list them in the README. They also have a bot 👍
• a github action with a slightly simpler idea to accomplish this https://github.com/marketplace/actions/contribute-list

Side note:

Listing all contributors in the book would be also nice (once we publish that :))

Comece revisando o README do repositório e as abordagens propostas allcontributors.org e contribute-list. Decida como os contribuidores, incluindo os que não contribuem com código, devem ser coletados e exibidos; considera-se concluído quando o projeto os reconhece publicamente em um local mantido, com a consideração do livro tratada separadamente.
