doc: Alphabetize long options for pg_dump[all].

The current ordering strategy for these pages is to list the short
options in alphabetical order followed by the long options in
alphabetical order. If an option has both a short variant and a
long variant, the short variant takes precedence. This commit
moves a few recently added options to match this style. We should
probably adjust all pages and --help output to list the long and
short options in one combined alphabetical list (with the long
variants taking precedence), but that is a much larger change, so
it is left as a future exercise.

Oversights in commits a5cf808be5, 1fd1bd8710, and bde2fb797a.
