Hi @TheRealMDoerr . Thanks for the review.

Github has now deployed new images that solve the problem, so this PR is no longer required, closing the PR then.

[Here's a test](https://github.com/vieiro/gha-macos-resolve-hostname/actions/runs/10558777738) to verify the images work properly with `getaddrinfo`.
