fetch discussion comment URL

[trag1c]

Closes #71

Irrelevant for the current state of the PR (so feel free to ignore this entire PR description), but in my issue I said this:

I had to deal with this in the past (for Ghostty bot actually lol) so I have a fix ready!

What I had to deal with was getting the node ID (DC_bO8RxDkUrw4=) from the comment ID present in URLs by manually constructing it. But since we already have the node ID, we can just request the entire comment URL… so yeah, I wasted like 30 minutes on making an explainer diagram for my original solution before realizing it's much simpler 🥲

I don't want it to go to waste, so I'm including it here for fun. Actually -- would it be useful to allow the URL comment ID to be passed into gh-manage-by-discussion rather than the GraphQL node ID?

Maybe so! I don't think its super critical because of how we call it but its nice.
