docs(arkv6x): note bootloader UART7/TELEM1 mapping (#27429)

* docs(arkv6x): note bootloader UART7/TELEM1 mapping

The ARKV6X bootloader enables only UART7 (TELEM1), but the existing
serial port table reflects the runtime mapping where /dev/ttyS0 is
GPS1. Users flashing firmware over UART with px_uploader.py hit a
dead end when targeting GPS1 because no other UART responds in
bootloader mode.

* docs(arkv6x): fix uploader script name and add link

Script is named px4_uploader.py in the Tools directory; link to it
on GitHub so readers can find it.

::: info
The mapping above applies to the running PX4 firmware. The ARKV6X bootloader enables only `UART7` (TELEM1), so when flashing firmware over UART with [`px4_uploader.py`](https://github.com/PX4/PX4-Autopilot/blob/main/Tools/px4_uploader.py) you must connect to the **TELEM1** port — no other UART will respond in bootloader mode.
