aprenda-go-com-testes card does not link to the project repo

🐞 **Problem**

(title)

🎯 **Goal**

Make the aprenda-go-com-testes project more accessible to users looking to contribute

💡 **Possible solutions**

In ``src/components/ProjectList/listOfProjects.js``, the aprenda-go-com-testes object does not have a ``projectLink`` property. It does, however, have a ``githubLink`` property, so I suppose the creator of the card confused ``projectLink`` for ``githubLink``.
This can be fixed by simply renaming the ``githubLink`` property for the object.
