tweak(org): honor default command when archiving

Change the binding for archiving to `org-archive-subtree-default`, which
is the recommend "catch-all" command in the org manual. The user can
specify the actual command in `org-archive-default-command`. The default
for this variable is `org-archive-subtree`, which we previously used for
the binding, so this commit changes behavior only for users who have set
`org-archive-default-command` explicitly.
