When creating a new project, initialize a git repository

[rigor789]

Is your feature request related to a problem? Please describe.

Majority of projects are managed using git - it's frustrating to have to init a git repo whenever creating a new project.

Describe the solution you'd like

When running ns create a fresh project should initialize a new git repository (git init) and commit the initial files. (git commit -m "Initialize new project").

Describe alternatives you've considered

Additional context

The git repository would not have a remote - this is up to the users to add.
A couple benefits of doing the init & initial commit:

• when creating a new project to reproduce an issue, it's clear what changes have been made, since the initial commit is coming from the template & subsequent commits are part of the repro.
• pushing a project to a new git repo is simpler
• less commands to run for any new project
• git is ❤️
