Add test that checks testnet config settings are up-to-date with testnet #715
Description
What problem does your feature solve?
The quickstart image contains testnet Soroban settings config in a JSON file, that gets used when using local mode so that local mode offers settings that are consistent with testnet:
https://github.com/stellar/quickstart/tree/main/local/core/etc/config-settings/p23
The settings are hardcoded into a JSON file so that the local image can be used without needing to contact the outside world.
Over time it gets out of date and we forget to keep it updated.
What would you like to see?
A scheduled and PR test that checks that the testnet config in the JSON file is consistent with testnet.
