I thought under Option 2 Raspberry 5 was supported

Yes supported, but why to bother to built it from source code, when packages for RPi are available from Flightaware. It is Ubuntu & Debian amd64 which are not available from Flightaware.

I tried the piaware-sd-card-8.2.img before but I got an error message saying the board did not support that.

Dont use piaware sd card image. First write Raspberry Pi OS Bookworm on sd card using RPi Imager and power up. Next go to the Flightaware site whose link I have given in my above post . There you will find commands to install piaware and dump1090-fa ver 9.0 pre-built packages. Very easy to install. Try it. If that fails, only then build & install the packages by method given at Github
