Local app dev. on linux section fix

[djkato]

Heyo, in https://docs.saleor.io/docs/3.x/developer/extending/apps/local-app-development#working-on-linux you claim that for development on linux, one needs to set change the network driver to host to work locally on an app, but that doesn't work.

Setting

networks:
  saleor-backend-tier:
    driver: host

throws error

─λ sudo docker compose run --rm api python3 manage.py migrate

The only way to work with apps locally on linux that works for me is to use is to use my local IP instead -
So instead of http://localhost:3000/api/manifest or http://host.docker.internal:3000/api/manifest
Using for example http://10.0.0.5:3000/api/manifest works for me.

I'd recommend maybe remove the Linux and windows difference all together and recommend to use that, as it becomes consistent between operating systems and requires setting only a single address for:

APP_API_BASE_URL=http://10.0.0.5:3000
APP_IFRAME_BASE_URL=http://10.0.0.5:3000
