Close GitHub Discussions and merge it to GitHub Issues

[suzuki-shunsuke]

I have opened GitHub Discussions, but I think we should close GitHub Discussions and merge it to GitHub Issues.

• Discussion can't be closed, so the status of Discussion is unclear
• Issues is dispersed between GitHub Issues and Discussions. We should gather issues into one place

  • A dictionary of templated variables in registry and query mechanizm #1673

Done.

😆 I was so confused. You can mark Q&A as answered, but otherwise yeah it's confusing to mark stuff as done. Makes sense to simplify but I did find it confusing as I thought discussions was better for "free form" discussion that didn't have a specific code related issue.

Thanks for documenting your change though in here so I didn't keep wondering where it went. You do a great job of communicating changes 👍🏻

Discussion can be closed now.

I changed the mind and reopened Discussions.
