feat: moves cloned repo to base folder

Description

When executing the command it throws an error saying `package.json` doesn't exists in destination folder:

This is because the cloned/extracted repository is put inside `${destination}/frontend-cookiecutter-application-master`.

What this PR does is move the content from `${destination}/frontend-cookiecutter-application-master` to `destination` as desired.

This way the problem is fixed and the repo is created in the desired location.
