Do not publish .git subdirectory to npm registry

[agavrilov]

Describe the bug
'.git' subdirectory is published to NPM registry in version 5.4.2. It contains hooks/README.sample. The presence of '.git' subdirectory triggers a bug in NPM which prevents the installation of other packages: npm/npm#17475

Expected behavior
'.git' subdirectory should not be a part of published version
