Fixes npm securtity warning of package tar

[csalmeida]

The issue #19, is related with dependencies used by gulp-sass. This PR updates package-lock.json changing the version of tar from v2 to v4.4.2, required to remove the warning.

The issue is also documented on other repos:

• node-sass/[Security] Vulnerability in tar
• gulp-sass/Dependency "tar" - high severity vulnerability
• node-gyp/updated tar package version to 4.4.8

The warning would show as follows:

                       === npm audit security report ===
