[stevenweaver]

Summary

• Adds compatibility for SLURM 24.11.0+ which removed the slurm_addto_step_list() helper function
• Manually constructs step list entries using slurm_selected_step_t for newer SLURM versions
• Maintains backward compatibility with older SLURM versions through preprocessor directives

Changes

• Modified slurm_drmaa/job.c in slurmdrmaa_job_on_missing() function
• Added version check for SLURM_VERSION_NUM(24,11,0)
• Replaces removed helper with explicit step list construction

Test plan

• Verify compilation with SLURM 24.11.0+
• Verify compilation with SLURM versions < 24.11.0
• Test job accounting queries with both versions
