It's not good to keep this in the test_runner because then we have multiple points that we need to edit the test config, which can be hard to find.
We need this because the module name for uniswap_v2 is so far different from the rest of the protocols.
* fix: add `balance_owner` attribute for ekubo_v2 components
* refactor: rename `ekubo` into `ekubo-v2`
* refactor: freeze `substreams-helper` version in ekubo V2 module
* docs: improve integration test comment
* docs: add TODO to remove `balance_owner` in favor of `AccountBalances`
