configs.gg23.audio: offer only sbc and aac as bluetooth sink codecs
A Pixel 9a with HD audio negotiated a high-quality codec, and WirePlumber
failed to create the bluez_input node ("mod.adapter: can't get format:
Invalid argument"), so no audio reached the hub and the phone retried
every second. With SBC it works. AAC decoding is available: the
nixpkgs pipewire bluez5 aac plugin links fdk-aac. sbc_xq shares the
sbc endpoint and has a decoder.
