Console warning is emitted every time you try to set a mimic joint's values

[EzraBrooks]

There are a number of systems and drivers that emit mimic joints' values, even though they are unnecessary, and there are even some systems that don't support mimic joints at all (like, last I checked, NVIDIA Isaac Sim) which make publishing the mimic joint status necessary.

As a result, the software I work on publishes mimic joints values, deliberately. Unfortunately with urdf-loaders this floods the console with warnings! Would it be okay if I submitted a PR to remove this console.warn call?

Yup! Makes sense -- feel free to make a PR.
