Add an output to let other steps know if something was pushed

[ewjoachim]

I'm a beginner in GH Actions, but if I understand it correctly, you could add an explicit output so that other tasks could run conditionnally based on whether this action pushed something or not.

You're right, this could be useful. I'll add some outputs, not just this 👍🏻

Yay thanks :) ❤️

Hi, I've added 3 outputs to the actions: committed, tagged, and pushed. They're pretty self-explanatory, but there's more info on the README and in the action manifest.
I've published this change in v5.3.0 (also accessible via v5 and latest), feel free to test it and see if it fits your needs ;)

I'm closing this issue for now, feel free to contact me if you find any bug 👍🏻
