Remove Googlebot block before going public

Googlebot (and other crawlers) are currently blocked in /opt/nginx/conf/bots.d/blacklist-user-agents.conf to prevent crawling during testing.

Remove the Googlebot/Googlebot-Image entries from that file and reload nginx before launch.

I removed all AI bot blocks, no point in giving Google a competitive advantage. Any future changes to this should probably be focused on blocking certain page ranges + adding more rate-limiting.
