commit 9c98812e8c68401c201719ce0c7a5ea67cd00f5d
Author: Marek Kasik <mkasik at redhat.com>
Date:   Thu Jul 27 17:03:41 2023 +0200

    glib: Add new members to PopplerCertificateInfo
    
    These new members of the structure can be used to show more detailed info about
    who signed the document and more info about issuer of the certificate.
    
    Add PopplerCertificateInfo to PopplerSignatureInfo to be able
    to get certificate info of the signature.
