man/dockerd.8: assorted formatting fixes

kolyshkin · corhere · commit 690d1666329b · 2024-08-05T17:38:50.000-04:00
Mostly, this makes sure that literals (such as true, false, host,
private, examples of options usage etc.) are typeset in bold, except for
filenames, which are typeset in italic.

While at it,
 - remove some default values from synopsis as it should not
   be there;
 - fix man pages references (page name in bold, volume number in
   regular).

This is not a complete fix, but a step in the right direction.
