ci: ansible-test action now requires ansible-core version

The ansible-test github action does not use a supported version
of ansible-core by default.
https://github.com/ansible-community/ansible-test-gh-action?tab=readme-ov-file#ansible-core-version

We have to set it in our action.  Using `stable-2.17` as that is the latest stable version.
