Upgrade website dependencies

Main reason to initiate this `next-update` campaign was that
https://github.com/o2team/hexo-renderer-scss/issues/1 has been fixed,
which I remember had bitten us in the past. Seems to no longer affect
us since we generate stats in Theme configuration, but it seemed like
an ok time or a dep-upgrade regardless
