Clarify configuration settings for Ender 5 Pro

[benjie]

This is my full make menuconfig:

(Top)
                                                         Klipper Firmware Configuration
[*] Enable extra low-level configuration options
    Micro-controller Architecture (STMicroelectronics STM32)  --->
    Processor model (STM32F103)  --->
[ ] Only 10KiB of RAM (for rare stm32f103x6 variant)
[ ] Disable SWD at startup (for GigaDevice stm32f103 clones)
    Bootloader offset (28KiB bootloader)  --->
    Clock Reference (8 MHz crystal)  --->
    Communication interface (Serial (on USART1 PA10/PA9))  --->
(250000) Baud rate for serial port
[*] Optimize stepper code for 'step on both edges'
()  GPIO pins to set at micro-controller startup

Makes sense, not sure why that config has not got the exact comms settings like most of the 4.2.x configs..

You will need to sign off your PR as per point 3 in https://github.com/Klipper3d/klipper/blob/master/docs/CONTRIBUTING.md#what-to-expect-in-a-review

Thanks

Not sure if it helps at all, but here's my full config which is printing very well for me currently. Klipper is an amazing upgrade from the onboard software the printer comes with! Took a full weekend to get everything up and running, but now it is, it's glorious!
