pupmod-simp-sssd `pup*-ad` acceptance tests failing (SSH could not settle on host_key algorithm)

Description

After tentatively fixing SIMP-7965, the simp-sssd pipeline now makes it far enough for all acceptance tests to succeed except for the jobs pup5.5.20-ad and pup6.16.0-ad, which now time out after repeatedly failing to connect to the ad via SSH with the error "Host ... unreachable: Net::SSH::Exception - could not settle on host_key algorithm."
