Fix whitespace in user, and misc, 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
woll render as being in a code block too, even if not
meant to. This fixes all these issues, and cleans up
minor whitespace issues in /user, /security, /ssh
and /migrate_ci_to_ce docs.

 1. Make sure your `pom.xml` file includes the following:
 
-    ```xml

-      <repository>
-        <id>gitlab-maven</id>
-        <url>https://gitlab.com/api/v4/projects/${env.CI_PROJECT_ID}/packages/maven</url>

 1. Add a `deploy` job to your `.gitlab-ci.yml` file:
 
-    ```yaml
-    deploy:

-      script:
-        - 'mvn deploy -s ci_settings.xml'

+       - master
+   ```
 
 1. Push those files to your repository.
