All: Disable comments on wpdocs sites

There were some 14,000 spam comments and pingbacks on api.jquery.com
pending approval from from last year alone. This given that API pages
are of type "post", and bots presumably submit these directly via
POST parameters despite no form being rendered.

Rather than setting this via wp-admin by hand, set this explicitly
here.
