fix: fix for node 24 and add to test matrix

[serhalp]

Summary

node.js 24 was released and moved to "Current" status yesterday, May 6 2025: https://nodejs.org/en/blog/release/v24.0.0.

This bumps verdaccio and jsonwebtoken to fix a fatal error on node 24 coming from this transitive dependency: https://github.com/auth0/node-jwa/pull/52.

While I was here, I did a bit of cleanup: for everything that isn't actually running vitest (prettier, etc.), just use the latest node.js LTS and always use the same alias (latest) for consistency.
