Upgrade Node.js version to 24.x

[shati-patel]

This upgrades the action to run on Node 24. This will unblock some dependency updates (like #1364), and also preempts the deprecation of node 20 (Deprecation of Node 20 on GitHub Actions runners).

I ran the build/tests and everything appears to work as normal 🤔

I also tried running a MRVA with this and it worked (or at least the errors weren't related to this branch)
