only publish the page resources that are actually used

Hugo used to publish every file of the page bundles, including the
source files (xcf, heic, raw videos, scripts, etc.), twice because of
the english articles copied in the french site. The site weighed 503 MB.

With publishResources disabled, only the resources referenced through
.Permalink / .RelPermalink are published: 95 files are no longer
published and the site now weighs 165 MB.

The few resources referenced by raw markdown links or by the figure
shortcode (which does not resolve page resources) now use the
attachedFileLink and attachedFigure shortcodes.

Note: Hugo 0.121 uses the _build front matter key (renamed build later).
