Fix whitespace in many administration 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 for many admin
docs in /high_availability and /auth (part 1)

     - `<your_oidc_label>` is the label that will be displayed on the login page.
