fix: client/server authentication failure on cloning repos

If 'Allow-CI+1' is triggered on a topic that contains changes
from different repos, for example from TF-A and CI repo, the
cloning script will correctly pick up the TF-A changes but
fail to pick the CI changes and throw the following error message:

 ++ /srv/shared/tf-a-gerrit-tforg-l1/3754/tf-a-job-configs/scripts/parse_refspec.py
 Warning: Permanently added '[review.trustedfirmware.org]:29418' (ED25519) to the list of known hosts.
 sign_and_send_pubkey: no mutual signature supported

The issue occurs because the SSH client refuses to use older ssh-rsa
keys after upgrading to Jammy. This error has been fixed by updating
SSH_PARAMS.
