manual: Avoid duplicate section headings.

There exist two "Examples" and two "Troubleshooting"
sections. Unfortunately the discount markdown converter is
unable to create a working table of contents section in this
situation: both links of the table of contents jump to the first
Examples/Troubleshooting section.

Fix this by renaming the sections.
