[doc] Point directly to Github page

We don't need to rely on the lowrisc.org re-direct because we can simply
point to the Github page itself.

 # Sonata system
 
-Sonata is a system for evaluating the usage of [CHERIoT Ibex core](https://github.com/microsoft/cheriot-ibex) as a microcontroller for embedded, IoT and Operational Technology applications.
+Sonata is a system for evaluating the usage of the [CHERIoT Ibex core](https://github.com/microsoft/cheriot-ibex) as a microcontroller for embedded, IoT and Operational Technology applications.
 The system contains a number of peripherals (I2C, SPI, GPIO, USB, and UART) and the CHERIoT Ibex core itself.
 It is designed for use on FPGA and specifically targets the [Sonata FPGA board](https://github.com/newaetech/sonata-pcb), but as the entire design is open-source (from PCB to software), it can be run on any similar system.
 
 This project is designed to look like a normal microcontroller in terms of usability, including SDK, examples, and normal capabilities such as debuggers.
 But underneath that the [CHERIoT](https://www.microsoft.com/en-us/research/publication/cheriot-rethinking-security-for-low-cost-embedded-systems/) capabilities provides a high level of "default security" that simplifies designing embedded systems in a secure manner.
