Update URLs with broken redirects

The organization of the pages under arduino.cc are in a constant state of flux. There is some attempt to set up
redirects from the old URLs, but this is done inconsistently, breaking the links to the previous pages.

 **This is a retired product.**
 
-The [Intel® Galileo Gen2](http://arduino.cc/en/ArduinoCertified/IntelGalileoGen2) supports shields that operate at either 3.3v or 5v. The board is designed to be hardware and software pin-compatible with Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the adjacent AREF and GND pins), Analog inputs 0 to 5, the power header, ICSP header, and the UART port pins (0 and 1), are all in the same locations as on the Arduino Uno R3.

 The Intel® Galileo Gen2 is programmed using the [Arduino Software (IDE)](https://arduino.cc/en/Main/Software), our Integrated Development Environment common to all our boards and running both [online](https://create.arduino.cc/editor) and offline. For more information on how to get started with the Arduino Software visit the [Getting Started page](https://arduino.cc/en/Guide/HomePage).
