This is required for the current CIS benchmark hardening configuration on Rocky based systems.

OpenSSH generates ed25519 keys by default since 9.5[1]. This conflicts
with the FIPS policy in the current RHEL release (9.4) which forbids
ed25519 SSH keys[2]. This prevents you from being able to access the
system.

Essentially we need to wait for RHEL to support FIPS 186-5 before
switching to ed25519.
