Hello @Manoramsharma cc @zong-zhe

Sorry, I don't think this issue has really been fixed. This PR #427 just remove extra only one blankline in the kcl.mod file.

1. kpm init some_pkg will generate a kcl.mod file containing three blank lines instead of one.

2. In the some_pkg folder, run kpm add k8s and kpm add helloworld will generate a kcl.mod file containing two blank lines instead of one.
