Disable WebKit integration (--html option)

This adds several "heavy" dependencies, notably WebKit itself, but also
video and spellchecking among others, which are undesired for a simple
interactive dialog.

The WebKit feature is disabled by default upstream, and several major
distributions (including at least the Fedora/Red Hat family, Arch and
openSUSE) don't enable it in their packaging, so portable software
cannot rely on this option being available. According to
codesearch.debian.net, none of the packages with a dependency on zenity
use the --html option.

The beginning of the Debian 13 cycle seems is a good time to make this
sort of potentially disruptive change; most likely nobody will notice
this feature going away, but if we get bug reports, we can consider
other options such as having a zenity-minimal package without HTML
support, or having a zenity-full package with it.

Closes: #777608, #942362
