chore: downgrade foundry version to match across workflows (#11017)

fix(workflows/protocol-devchain-anvil): downgrades foundry version

This should match the version set in `protocol_tests.yml`.
This PR downgraded the foundry version, but CI didn't catch the failing workflow on the feature branch, because `protocol-devchain-anvil.yml` only runs on `master`.
