"In a valiant effort to restore functionality, developers revert to stable Node.js version to tackle pesky test failures!"

Commit Details:

fix: downgrade node version in CI to fix tests (#2278) ## Why is this change needed? CI is broken because there's some issue with proto serialization in node 22.7.0. I used the same version that's in the hub deployment dockerfile. https://github.com/protobufjs/protobuf.js/issues/2025 ## Merge Checklist _Choose all relevant options below by adding an `x` now or at any time before submitting for review_ - [x] PR title adheres to the [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) standard - [ ] PR has a [changeset](https://github.com/farcasterxyz/hub-monorepo/blob/main/CONTRIBUTING.md#35-adding-changesets) - [x] PR has been tagged with a change label(s) (i.e. documentation, feature, bugfix, or chore) - [ ] PR includes [documentation](https://github.com/farcasterxyz/hub-monorepo/blob/main/CONTRIBUTING.md#32-writing-docs) if necessary. <!-- start pr-codex --> --- ## PR-Codex overview This PR updates the Node.js version in the CI workflow to 22.4.1 due to an issue with 22.7.0.
