Hey Scott, thanks! I'll review this once I am back at work on the 6th January 2025.

So, my hesitance in accepting this is that it conflates "newer" with "better". The versions of the dependencies we have now work and don't have any vulnerabilities that cause issues. I'm pretty OK with keeping the dependencies as is; upgrading poses risks (breakages, introduced vulnerabilities in newer versions or bugs) and little upside (we intentionally want the behavior to stay exactly the same).

If this were software-as-a-service, where fixing a broken deploy was cheap, I'd be more open to it - but this is an executable that's not intended to be updated by users frequently. Releasing a release with bugs is difficult to fix since it's not baked into a package manager. For what it's worth, we intentionally vendor all of these dependencies internally
