Doc: Add a warning about versions 2.0.2 and later of the Raspberry Pi Imager not working properly

[INeedCaffeine]

Description

FRC Team 6413 ran into problems trying to write the 2026.1.1 image using the Raspberry Pi Imager tool. After some investigation we discovered a bug was introduced in v2.0.2 of the imager tool which prevents it from writing the PhotonVision images to any SD card on any Windows 10 or Windows 11 computer.

Attempting to write a custom image (.img and .img.xz) results in the following error dialog appearing as soon as the write action is confirmed:

Versions 2.0.0 and earlier will successfully write the image files to the selected SD card.

We'll just update this later if they fix it

This does not seem to be a problem on macOS, since I have been successfully writing PV images with RPi Imager v2.0.3.

FWIIW ... 2881 is a Windows-only crew across our team software tools and we have just used Rufus (portable) for years in place of etcher, rpi imager, or other solutions. Never have had one issue and it is super fast / dead simple just like the other tools. Pick your SD card drive, pick your .img file, and go. It has been maintained/loved over many years now.

You might want to consider updating the documentation to suggest fallback alternatives for specific platforms (win, mac, *nix) to the primary recommendation of RaspberryPi Imager when things aren't working out.
