feat: Add test for UniswapV2

- Used a random post-Shanghai-created USV2 pool state with enough liquidity for the test

Necessary fixes:
- Don't hardcode to EVMPoolState
- Don't expect adapter to always be set.
- UniswapV2 names its module differently for some reason... this seems like a special case so instead of updating all integration test yamls, I'm just hardcoding it in test_runner.rs. Perhaps not the best decision?
- Log the static attributes if not found.
- Get the substreams yaml path from config instead of hardcoding it.
