ci: bump foundry to 2024-08-04 nightly

[evan-gray]

We have seen some instances in CI where anvil returns a block number which doesn't match the one queried. Perhaps this issue has been fixed since the nightly currently being used (2024-05-26). Confirmed that the forge output is still the same by exec-ing into the container and running the following before and after the change then diffing the result.

cd ~/app/ethereum/build-forge
find . -type f -exec sha256sum {} \;
cd ~/app/relayer/ethereum/build-forge
find . -type f -exec sha256sum {} \;

thanks for checking the build output, other than that this should be a straightforward change

Just hit this error so perhaps the bump does not resolve it, but may be worth considering nonetheless.

Isolated the bug and reported

updated to a version which includes the fix and checked the build output again
