Fixed link to federation policy

Currently, the rendered docs link to a =.cf= page
(https://docs.cfengine.com/docs/3.15/cfe_internal/enterprise/federation/federation.cf#semanage_installed),
but actually the url should target an =html= page
(https://docs.cfengine.com/docs/3.15/reference-masterfiles-policy-framework-cfe_internal-enterprise-federation-federation.html#cfengine_enterprise_federation-semanage_installed).

I could not figure out how to link to the specific heading.
