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.

    subjective, and you can use the default value which is to never expire:

-    ```
-    git filter-branch --force --tree-filter 'rm -f path/to/big_file.mpg' HEAD
-    ```
+   ```
+   git filter-branch --force --tree-filter 'rm -f path/to/big_file.mpg' HEAD
+   ```
 
 1. Instruct Git to purge the unwanted data:
 
-    ```
-    git reflog expire --expire=now --all && git gc --prune=now --aggressive
-    ```
+   ```
+   git reflog expire --expire=now --all && git gc --prune=now --aggressive
+   ```
 
 1. Lastly, force push to the repository:
 
-    ```
-    git push --force origin master
-    ```
+   ```
+   git push --force origin master
+   ```
 
 Your repository should now be below the size limit.
