WIP: Use Sequoia in RHEL 10 instead of GPG

[vojtapolasek]

Description:

• create a new rule package_sequoia-sq_installed
• enhance rule ensure_redhat_gpgkey_installed so that it uses the sq command instead of gpg n RHEL 10
• check for new PQC key in RHEL >= 10
• The build system ordering takes care that the sq package is installed so that it can be later used. So in case rule ensure_redhat_gpgkey_installed exists in the profile, the rule package_sequoia-sq_installed should be present in the profile as well.

Rationale:

• There are two reasons for this change.
  • there is a new RPM release key in RHEL >= 10 and it needs to be checked that it exists
  • in case this key is shipped, the regular gpg command cannot handle it and it needs to be inspected with the sq command

Question to be answered: Is the new PQC key going to be present always or only sometimes?

Review Hints:

Test with Automatus. But ensure that the RHEL machine contains all three keys.
