Update roadmap.md

[bitsondatadev]

Removing completed or stale projects from the roadmap while adding more relevant projects that are actively being worked on.

Removing the notion of priority since not everyone uses it, and it also has no indication of something actually getting done or not. I think it's best to just learn what the priority is based on what has been updated recently.

Eventually, we should move to the newer projects which has a roadmap layout that will make this stuff a bit more explicit.

@Fokko we should discuss how we chunk up your work in pyIceberg

Thank you for update this!

[Fokko]

Left some small issues, but this is much better than what we have today. Thanks for picking this up! 🚀

@bitsondatadev I just noticed this one, can you resolve the pending issues? You put in so much effort already, it is a waste to keep this lingering here.

Hey all, I'm looping back to this today.

Hey all, I'm looping back to this today.

There are lies, damned lies, and random promises I make on GitHub. Pardon my 🧠.

Just one open question but we can update the answer on the next round of changes.

I'll be proposing a few changes in the next community sync.

I'll merge this since this is such an improvement over the current state. If there are any follow-up questions, we can address them in a new PR. Thanks @bitsondatadev for taking the lead on this 👍
