Implementation proposal for godotengine/godot-proposals#2559 (Sorry maintainers - I don't know how to properly link this PR to the proposal)

if verbose is set, then print command invoked during export

Bugsquad edit: This closes godotengine/godot-proposals#2559.

@Calinou Oops! I accidentaly created zombie, duplicated "Server Builds" action. Sorry! :-( Hope that can be undone (I already reverted the change from my fork that caused that). I leave it as is to avoid more damage, sigh

As far as I know, GitHub Actions will leave it there permanently, so there's nothing that can be done about it. No worries 🙂

I was thinking about this again and it's probably a good idea to always print these messages on export. This would mean using print_line() instead of print_verbose().

After making this change, please squash commits together into a single commit so we can merge this.

The functionality is already provided by #84779.
