This change uses the suggested steps in https://support.crowdin.com/cli-tool/#debian, with a slight modification in creating the `crowdin.list` file in the `/etc/apt/sources.list.d` directory. This approach creates a new file for `crowdin.list`, then pipes the content to `tee -a`. Credits go to [this Ask Ubuntu thread reply](https://askubuntu.com/questions/185268/permission-denied-etc-apt-sources-list/185270#185270).
