Add publishing workflow

We also need to namespace the editorial workflow with `civictheme_` prefix, so it becomes `civictheme_editorial`.

But there is an issue with https://www.drupal.org/project/drupal/issues/3088534 🐛 The view installed by content moderation assumes the 'editorial' workflow installed by standard profile exists Needs review that assumes `editorial` workflow for the view installed by the install profile.

We need to do the following:
1. Identify where the view is installed from - standard profile or workflow moderation module etc.
2. Update this view to use `civictheme_editorial` workflow and update all filters.
3. Export the view and ship it as `config/install` config (required config since this becomes a core CivicTheme's feature).

We may also need to create an update hook for existing editorial workflows, but it would be more consistent to simply apply the configuration shipped in `config/install` to the existing site and overwrite their existing view config.
