Signed-off-by: Jacob Dahl <dahl.jakejacob@gmail.com>
* docs(arkv6s): add product photo and note single-IMU variant
Drop in docs/assets/flight_controller/arkv6s/ark_v6s_front.jpg
so the page renders the board photo it already references, and
align the intro with the upstream description by spelling out
that the V6S is the single-IMU variant of the V6X.
* docs(arkv6s): add bootloader UART note, fix arkv6x RAM typo
Add the bootloader serial port note (TELEM1-only in bootloader mode)
to the ARKV6S docs, matching the ARKV6X docs. Also fix the ARKV6X
MCU spec listing "1MB Flash" instead of "1MB RAM".
