Add "Duplicate Project" button to the project manager

[CarpenterBlue]

Describe the project you are working on

A slice of life game about nuns living ordinary lives.

Describe the problem or limitation you are having in your project

I keep reusing same template project over and over and I would mightily appreciate it if I could do it from Project Manager.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

I keep reusing same addons, same settings, same stuff over and over. Usually, it means I have to go to file system and make a copy manually.
I would enjoy button in the project manager.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Under the manage, tags, there would be new button to duplicate project.

If this enhancement will not be used often, can it be worked around with a few lines of script?

I am doing it manually right now but it being button in the project manager would promote reusability of addons, templates and such in the Godot ecosystem.

Is there a reason why this should be core and not an add-on in the asset library?

I don't think it's possible to make add-ons for the project manager. Maybe as separate app?
Can be done manually or with command line.
