With prebid/Prebid.js#13885 Prebid.js populates the
hb_vertargeting key with a specific PUC version. This updates most references to@latestso that they use that key instead.Note that everything that's not JS has no equivalent as of yet. I chose to still replace @latest with "a specific version", figuring that unless we stop recommending it we will never get off it. An exception is AMP, that I left untouched, as I'm still trying to figure out if it's possible to pass targeting from
<amp-ad>.
