Documentation links pointing to HTTP mode rules are broken

[insanitywholesale]

In the following pages in the linked section:

• https://prometheus.github.io/jmx_exporter/1.2.0/java-agent/http-mode/#advanced-yaml-configuration
• https://prometheus.github.io/jmx_exporter/1.1.0/java-agent/http-mode/#advanced-yaml-configuration

The link to see the HTTP mode rules returns a 404

@insanitywholesale Thanks for the issue. This should now be fixed.
