Fix whitespace in topic, university, workflow docs

Many code blocks are 4spaced, and they render in GitLab
without coloring as a result, even though they are
fenced with a language label. If in a list, other items
will render as being in a code block too, even if not
meant to. This fixes all these issues, and cleans up
minor white space issues in /topic, /university, /update
and /workflow docs.

 1. Start Unicorn and PostgreSQL so that we can prepare the schema:

+   sudo gitlab-ctl start unicorn

+   ```bash
+   sudo gitlab-rake db:create db:migrate

 1. Stop Unicorn to prevent other database access from interfering with the loading of data:
 
-    ```bash

 After these steps, you'll have a fresh PostgreSQL database with up-to-date schema.
