Fixed change initiative skill when choosing perception in Pf2e

[DawidIzydor]

The macro for changing initiative skill for Pf2e doesn't work in choosen "Perception" from the first menu.

Perception is not a skill per se in Pf2e, and the actor.data.data.skills does not contain a "perception" field. Perception is in the actor.data.data.attributes.perception instead.

These change fixes this issue
