docs(airfoil): update dataset_slurm_airfoil __main__ docstring

Brings the command line argument descriptions up to date with all current
arguments, including the previously undocumented -account, -type,
-minutes_per_sim, -n_slurm_array, and the new --field_output flag.
Adds defaults to each entry for clarity.
