function Theme::getInstallDirectory

Returns the directory where a theme should be installed.

If the theme is already installed, \Drupal::service('extension.list.theme')->getPath() will return a valid path and we should install it there. If we're installing a new theme, we always want it to go into /themes, since that's where all the documentation recommends users install their themes, and there's no way that can conflict on a multi-site installation, since the Update manager won't let you install a new theme if it's already found on your system, and if there was a copy in the top-level we'd see it.

Return value

string The absolute path of the directory.

        // When installing a new theme, prepend the requested root directory.
