CLN: Remove unused param

[alimcmaster1]

Param no longer used. Can remove it from single caller of this function

[jreback]

so rather than do this, I would make the signature more similar to ....numeric_binop and pass op, then construct the opstr inside.

@jreback I think this is feasible only after merging #22336 and replacing np.abs with operator.abs (no idea whether this has any side effect), because np.abs.__name__ is "absolute", not "abs".

[jreback]

closing as this is dependent on #22336 which needs to be fixed first.
