[REF] website_*: Change registerTours of tour_utils

As steps are encapsuled in an arrow function from
69a5d8e3ce47238 for steps tour definition to avoid
direct Markup(_t()) interpretation, the same is done
for registerWebsitePreviewTour() of
"odoo/addons/website/static/src/js/tours/tour_utils.js"
in this commit.

This is done in anticipation of the use of
_t() (import from @web/core/l10n/translation) with
registerWebsitePreviewTour().
