docs: fix trailing whitespace from markdown and regenerate

Trailing whitespace in Markdown can force line-breaks, which doesn't seem to
be the intent on these;

    find . -type f -print0 | xargs -0 perl -pi -e 's/ +$//'

The trailing whitespace also can cause the YAML to go wonky (although the
cli-docs-tool now takes that into account), and caused the "examples" section
to be missed in the `docker compose pull` page (something we should fix in
the tool).
