Update the NGINX guide

- The PHP version included with Raspbian 12 is 8.2. Update version numbers accordingly
- Consistently use systemctl for service management
- Include fastcgi settings discussed in issue pi-hole#962
- Remove basic auth configuration since Pi-hole webpage has authentication
- Remove autoindex setting as this is already the NGINX default
- Remove permission steps that are already handled by the Pi-hole install
