FreeRTOS Readme and examples needs to update?

[board707]

Hi

It seems that FreeRTOS library (libraries/FreeRTOS) Readme description is outdated. For example, it startes with the requirement, that the file RP2040_FreeRTOS.h must be included in the sketch first, while there is no such file in the library at all.

As about the examples, the one MultiCore-FreeRTOS seems to work, but staticMultiCore-FreeRTOS doesn't. If you take the latter code, and load it into the board - the LED lights up and does not blink, and the serial port freezes and the board is no longer detected by Windows.

The README.md was untouched from the original port-of-a-port so please ignore anything it says. :)

For the example, it does work but it's got race conditions such that as soon as a task gives up a mutex it re-grabs it before the other task can take it, so the led doesn't blink. Adding a delay(1) to the end of each while takes care of this, so I'll throw a PR up for it. Also change the default output to the USB port, not UART0.

Thank you very much, after adding the delay the example works fine.

Addition.
Also I think that the test should be named staticSingleCore-FreeRTOS, because it seems do not use a second core...
