[skip changelog] Update all mentions of Arduino Pro IDE (arduino#1966)

The Arduino Pro IDE application was mentioned several places throughout the documentation. That project became Arduino
IDE 2.x 1.5 years ago while still in the alpha development phase.

All users of the project will now know it by the name "Arduino IDE 2.x", so the documentation should do the same.
