GN: Trim newlines in markdown help blocks

In markdown mode (--markdown) GN puts the actual help text into fenced blocks.
Newlines at the beginning or end of such a block are not stripped and appear
in the generated HTML output, taking up vertical space.

This change ensures that newlines at the start and end are removed.
