Git - Improve missing Git user/name behavior

@CoreTechnologyAG @GuilhermeAbacherli I know how to resolve it, the reason why I opened this issue is because i think it can be done better. @eamodio could you take a Look at our suggestions? They are as following: Suggestion 1: Make an option in the settings to enable/disable auto-detect Suggestion 2: Make it a Warning instead of an error (Like git does as well) Suggestion 3: Give us the option to set user.name and user.email directly from VS Code (By @mrwensveen and @abby-d )
