Major updates for my personal use

[mrexodia]

My goal is to incrementally back up a few specific repos in my org, you can see my script here: https://github.com/mrexodia/x64dbg-repo-backup.

To that end I added support for the following:

• Add --token-from-gh to use the gh CLI tool for authentication
• Support discussions (closes Discussions not backed up #290)
• Support pull request reviews (closes Does Not Include Reviews #124)
• Move last_update to be per-resource (closes Backuping up multiple repositories but not the whole account #62)
• Minor optimizations to reduce redundant fetches

This is likely not going to be in a shape where you want to merge it as-is, so feel free to cherry-pick the commits you like or use it as inspiration. I tested it locally and it gets me the data I need so I'm happy with it, thanks a lot for your project! ☺️

I'd be willing to pull this in (or at least parts) if you separated this out into distinct features that make it easier to review.

[mrexodia]

The commits are (except maybe the last one) atomic so you can cherry-pick them and get the individual fixes you want 🙂

The commit e03e162 that addresses #62 moving to a pre repo last updated is a good change and addresses the items raised in the issue. Gets my +1.

[josegonzalez]

Please separate these into separate pull requests. If you don't want to, someone else is free to do that work for you and I will review them.

The problem is that all the commits are dependent on each other because of changes to the README/CHANGELOG, so splitting them is non-trivial.

Could you take a quick glance at the approach taken in 98ead29 (it introduces GraphQL). If you are not planning to merge that there is no point for me to upstream since I have to maintain a perpetual fork anyway for my own use.

[josegonzalez]

That looks fine. Only comment I would say is asking if we can split the graphql queries into a different file.
