Inactive projects do not have prolonged GPG keys

[xsuchy]

I found that lots of Copr projects has expired keys. E.g.:

I investigated one:
https://copr.fedorainfracloud.org/coprs/adelton/cryfs
This is project that have newest build 4 years old. But it seems to be still used even for recent Fedora. But the gpg key is:

check-gpg-key.py copr-adelton-cryfs.gpg 
Error: the key copr-adelton-cryfs.gpg expired at 2023-04-02 18:19:49+00:00

I used this script to check https://github.com/xsuchy/distribution-gpg-keys/blob/main/check-gpg-key.py

Right, we actually prolong keys... but the public key is only copied to backend from keygen with new builds. Plus note #2894

[praiskup]

@xsuchy already copy-pastes all the pub keys into distribution-gpg-keys-copr.rpm. At this time, we could automatically update all the out-dated pub keys on the backend side?

FTR: We prolong "year before expiration" of the old key.
