Explicitly force the platform within the docker pull action of the Makefile

[iamphilrae]

This fixes an issue on MacOS with an M-class processor. Without this, the following error was being returned when trying to run make serve:

chirpstack-device-profiles % make serve
docker pull chirpstack/chirpstack-device-profiles:latest
Error response from daemon: no matching manifest for linux/arm64/v8 in the manifest list entries: no match for platform in manifest: not found
make: *** [serve] Error 1 

With this fix in place, the app runs as expected:

chirpstack-device-profiles % make serve
docker pull --platform=linux/amd64 chirpstack/chirpstack-device-profiles:latest
