Update google.py to remove the native word

A lot of Gemini models are native image out or native audio, so this rule was raising too many false positives.

Can this go in the Gemini cookbook styles? the change doesn't seem Google-wide.

It can't, they are not the same thing. We're applying both styles at the moment... I could merge both into one, but that's way more work and I thought that we were the only ones using this script anyway...
