Macos runner: getaddrinfo ENOTFOUND downloads.gradle.org

A not insignificant percentage of my GitHub Actions runs on macos fails with

Run gradle/wrapper-validation-action@v[1](https://github.com/eygraber/cmp-library-template/actions/runs/7458677158/job/20293112859?pr=2#step:5:1).1.0

Running it again usually solves it, but this is very annoying. Happening for months now, but it's getting worse since I run more actions on macos recently.

This should be fixed by #167
