Update status_carp.php to include a link to The pfSense Book, rather than the community maintained documentation
Presently, at status_carp.php, there is a help button (circle with question mark inside of it) that links to the public, community maintained documentation. However, the pfSense Book documentation is more informative and also publicly available.
Link currently points to: https://docs.netgate.com/pfsense/en/latest/monitoring/carp-status.html
Link should point to: https://docs.netgate.com/pfsense/en/latest/book/highavailability/verifying-failover-functionality.html#check-carp-status (or https://docs.netgate.com/pfsense/en/latest/book/monitoring/carp-status.html.. see #10009)
For example, the pfSense book includes information that the current link does not.
