Reimplement crash reporting once Thrive creates them again

As it was removed in the version that upgraded to Godot 4.

Impeded until reimplemented in Thrive.

As an improvement the crash reporter should read the server response on failure and show it.

I'll note that I put in text to explicitly call out that Thrive doesn't generate crash reports currently so that text needs to be disabled when this works again.
