Migrate to openpgpverify

[yselkowitz]

openpgpverify (which uses Sequoia PGP) has been added as a replacement for gpgverify (which uses GnuPG):

https://fedoraproject.org/wiki/Changes/Sequoia_openpgpverify

ELN packages which use gpgverify should be converted to openpgpverify so that the former can be dropped.
