Add Entrust G4 Root

Entrust submitted a request to include the 'Entrust Root Certification Authority - G4' root certificate in Mozilla's CA program. The request underwent several reviews and updates to the Certificate Policy Statement (CPS) to address compliance with Mozilla's policies and the Baseline Requirements. Key concerns included domain validation practices and liability limits, which were subsequently resolved through updates to the CPS. The request was ultimately approved, and the root certificate was included in Mozilla's trusted root store.
