Add .gitginore to Module Scaffolding

[kresnasatya]

Hi there! I have been using this package for couple months. Let's say I installed module called Ticketing. Inside of it there are Modules/Ticketing/resources/js/app.js, Modules/Ticketing/resources/sass/app.scss, composer.json, package.json. This mean that we can install isolated dependencies inside of Ticketing module without polluting or mixing it with the root project.

As we know, if deps installed it will generate the node_modules and vendor directories. Those of directories are not ignored. So, when we switch git branch (for example), the node_modules and vendor from Ticketing module will be exposed. I think it's better to set default .gitignore each time module is generated. 😉

I know we can do it manually after generate module. But, as we know sometimes humans tends to forget and sometimes we believe that this package cover this case but it doesn't (yet). Also, I want to help to make this package much better.
