The text itself is fine, but I'm not sure, if this won't "over advertise" the project contributor role a bit.
We already have a huge number of project contributors, and just from my gut feeling, only half of them need the role, because they are managing labels or actively ask for review.
To make it clear, that this role is only needed in the mentioned cases, I would rather move it to an "optional next steps" section. I think otherwise it could be mistaken as a mandatory step and we miss the chance to describe what the role is needed for and what it entitles for.

What do you think @FaGru3n?

good point same "gut feeling" on myside... also while writing it, it was a bit strange to take this as a starting point in a foss community.

will modify it, with explaination how the contributor role is for... such if you want to add this and this you need to become a contributor in our project.

I guess for the many access permissions in former working models all new shifting people think they need a request for access.
