paperless: remove package & module as it has been superseded by paperless-ng

The paperless project has moved on to paperless-ng and the original
paperless package in Nixpkgs has stopped working recently (due to
version incompatibility with the providede Django package).

Instead of investing more time into the old module we should migrate all
users to the new module instead.

 ## Backward Incompatibilities {#sec-release-21.11-incompatibilities}
 
+- The `paperless` module and package have been removed. All users should migrate to the
+  successor `paperless-ng` instead. The Paperless project [has been
+  archived](https://github.com/the-paperless-project/paperless/commit/9b0063c9731f7c5f65b1852cb8caff97f5e40ba4)
+  and advises all users to use `paperless-ng` instead.
+
+  Users can use the `services.paperless-ng` module as a replacement while noting the following incompatibilities:
+    - `services.paperless.ocrLanguages` has no replacement. Users should migrate to [`services.paperless-ng.extraConfig`](options.html#opt-services.paperless-ng.extraConfig) instead:
+     ```nix
+     {
+       services.paperless-ng.extraConfig = {
+         # Provide languages as ISO 639-2 codes
+         # separated by a plus (+) sign.
+         # https://en.wikipedia.org/wiki/List_of_ISO_639-2_codes
+         PAPERLESS_OCR_LANGUAGE = "deu+eng+jpn"; # German & English & Japanse
+       };
+     }
+     ```
+
+    - If you previously specified `PAPERLESS_CONSUME_MAIL_*` settings in
+      `services.paperless.extraConfig` you should remove those options now. You
+      now *must* define those settings in the admin interface of paperless-ng.
+
+    - Option `services.paperless.manage` no longer exists.
+      Use the script at `${services.paperless-ng.dataDir}/paperless-ng-manage` instead.
+      Note that this script only exists after the `paperless-ng` service has been
+      started at least once.
+
+    - After switching to the new system configuration you should run the Django
+      management command to reindex your documents and optionally create a user,
+      if you don't have one already.
+
+      To do so, enter the data directory (the value of
+      `services.paperless-ng.dataDir`, `/var/lib/paperless` by default), switch
+      to the paperless user and execute the management command like below:
+      ```
+      $ cd /var/lib/paperless
+      $ su paperless -s /bin/sh
+      $ ./paperless-ng-manage document_index reindex
+      # if not already done create a user account, paperless-ng requires a login
+      $ ./paperless-ng-manage createsuperuser
+      Username (leave blank to use 'paperless'): my-user-name
+      Email address: me@example.com
+      Password: **********
+      Password (again): **********
+      Superuser created successfully.
+      ```
