Fix small docstring issues on pysmurf-controller tasks

[BrianJKoopman]

Description

This PR just fixes some argument ordering and method signature issues. I reordered the param decorator on set_biases to stay consistent with the argument ordering.

Motivation and Context

I noticed the issues while reading these docs for implementing something in sorunlib.

How Has This Been Tested?

Not tested, mostly just changes in docstrings. No removed code.
