[FEATURE] - "create project" command

[EnriqueGlv]

Hi !
I think that a great improvement to the project would be to add a command "create project" in order to automatically initialize a project with a tag, a source folder, and then open it in a new window.
However, I wanted to implement it myself and open a PR, but I saw that part of the project (the sub-module project-manager-core) isn't open-source, so I am not able to run the extension for developing.
If you agree to grant me an access to the private sub-module, I will be very pleased to contribute to your project.
Overall, thank you very much for your work, this vs-code extension is awesome !
