The particular steps are simple, but updates are infrequent enough that I need a refresher every time. Here's how I set everything up...

OctoPrint should have the Firmware Updater plugin installed, and the Raspberry Pi needs the avrdude binary available (if not: sudo apt install avrdude). In OctoPrint, go to the plugin settings for Firmware Updater and paste the link to the .hex file from the Prusa Github Release Page in the “from url” field. The wrench icon in the top right corner of the window controls how the firmware is flashed. The Prusa uses the avrdude flash method, the AVR MCU is ATmega2560, path to avrdude is /usr/bin/avrdude, and the AVR programmer type is wiring.
