workflow-syntax-for-github-actions.md: services.image: document empty image

Why:

Closes: N/A

What's being changed (if available, include any code snippets, screenshots, or gifs):

This is a follow-up of GH Actions community discussion #109389 - Conditional GHA jobs services and documents this undocumented solution that works great 🙂.

In the absence of jobs.<job_id>.services.<service_id>.if, this '' behavior is extremely useful and I would have loved to find it in the doc.

@ronjouch Hello, and thank you for patience while our team reviewed! 👋 After review, our team assessed this seems to be a very specific case. We are unable to cover every edge case in our documentations, and will not be able to add this update 💛

I'm going to go ahead and close this PR now. Thank you for your interest in improving the docs! ✨

@nguyenalex836 I beg to differ. This is not "edge case" land to me, it's the only way I was able to make my service conditional. Without lucking out on getting the tip about '' from the community, I'd have had no idea this was feasible 😕.

I'd love if GHA had explicit support for conditional services, but in doesn't. Until it does, please reconsider documenting this.
