@augustoproiete adding as a contribution for maintenance would be wrong in this case, this is for the main maintainers of a repository.

Your contribution falls more in the line of updating documentation.

@all-contributors please add @augustoproiete for doc

No worries. I thought maintenance was "chore" which is how I see updating hundreds of READMEs to point to GH Discussions 😄

Completely understandable, and there are probably people that use the maintenance label from allcontributors in that way as well.
Personally, I prefer it to be as distinct as possible, so you added a documentation change and doc would be appropriate then. You have also added an issue with the idea of updating the addin to support Cake 1.0.0, and once that issue is closed a new label would need to be added as well with the idea label (only an icon would be different in the README though).
