use more verbose syntax for compat with newer docker-compose

[mkuettel]

When running bin/build.sh and bin/start.sh afterwards with a newer docker-compose (in my case 2.24.0) it fails to decode the generated diva.yml file and it seems it wants the more verbose syntax.

 ⇒  Pulling /home/mogria/Code/diva-packaging/diva-dockerized/build/domains/testnet.local…
Running privileged command
   docker compose -f ./diva.yml pull
62 error(s) decoding:

* 'services[explorer.testnet.local].depends_on' expected a map, got 'slice'
* 'services[explorer.testnet.local].ports[0]' expected a map, got 'string'
* 'services[i2p.http.testnet.local].ports[0]' expected a map, got 'string'
* 'services[i2p.http.testnet.local].volumes[0]' expected a map, got 'string'

....

Therefore I adjusted the JavaScript code which generates it to use the more verbose newer syntax.

Afterwards running bin/build.sh and bin/start.sh works like a charm.

This is a draft as I'm not sure wheter I set all the additional keys correctly.
In particular theres the protocol: tcp key, but we might also want udp for i2pd. I'm not sure if mode: should be ingress

Then theres the depends_on thing, there are now new possibilities about restarting and those might be duplicate with the keys in the node service definition
