Update freertos version

[nguyen-v]

Hi, thank you for making this project available. I'm currently using the FreeRTOS module, but it seems the latest version available is v10.5.1. However, I need to use features that are only available for v10.6.x +. Is there an easy way to update the FreeRTOS kernel version?

Yes, here: #1265

I'm currently blocked on the FreeRTOS+TCP examples for which I don't have the right hardware (and there's no Nucleo-144 example).
