Summary

Added note about new authentication key path specification methods for Slurm 25.11+ while maintaining backward compatibility

Security assessment

This change documents new command-line options for specifying authentication key paths (--jwks-file and --key-file) as alternatives to environment variables. While authentication is a security concern, this appears to be a feature enhancement rather than addressing a specific security issue. The documentation update helps users implement secure authentication methods.

+###### Note
+
+For Slurm 25.11 or later, you can use `sackd --jwks-file <path>` and `sackd --key-file <path>` to specify authentication key paths instead of the `SLURM_SACK_JWKS` environment variable. The `SLURM_SACK_JWKS` approach remains supported for backward compatibility with Slurm 25.05 clusters.
