Summary

Updated Slurm version references from 25.05.4 to 25.05.5 and added new installer entries for Slurm 25.05.5-1 and 24.11.7-1

Security assessment

Added new installer versions with SHA256 checksums. Maintaining updated checksums prevents execution of tampered installers, addressing supply chain security risks. The explicit checksum verification instructions mitigate MITM attacks.
