Don't create /continue on macOS

[vadi2]

sudo touch /continue does not work on macOS as the root is a read-only filesystem.

Wouldn't an even better suggestion be to end all shells in the tmate session (e.g. via Ctrl+d) thereby ending the tmate session? That should end action-tmate, too, without any concerns about read-only filesystems.

Sorry, not sure I'm on the same page here - I don't want to end the tmate session, rather I want the github workflow to continue while the tmate session is available.

Okay, got it. I had not realized that continue didn't end the session.

I'm curious, though, how useful this feature is, as you'll typically be in the middle of things when the workflow finishes and your tmate session is forcefully stopped, no?

That will happen, definitely.

How I arrive at this situation is that I inserted the workflow in one particular step, I used tmate to fix it, but I didn't move the workflow down to another step when I re-ran the build and I got another error elsewhere. In this case it's still quite useful to have the session hang around, see the next error, and quickly diagnose it before the workflow finishes.

I wonder, then, whether we want to change the post-Action code we added for the detached mode: currently it exits when the continue file exists, i.e. it lets the workflow finish (force-stopping tmate). We probably want to treat it as if the user "switched to detached mode", until detecting that the tmate session was ended by the user.

Sorry for the long delay, I meant to take care of this idea but seem to never find the time. But that should not have blocked this here PR.
