The idea is that we don't need to clone full website repo when releasing. Instead, we can use a shallow copy, which is faster to get and costs less server and local resources. This applies to: * Website releases in `Jenkinsfile`. * Removing websites and making them the standard visible one, in the release process documentation. We can do a shallow clone by adding `--depth 1 --no-tags` when doing `git clone`. See also https://git-scm.com/docs/git-clone.
