Hint which repo an issue will be opened in

Testing #2095

I think it would be helpful if the new issue form editor would tell me which repo the issue is being opened in, just to give me confidence that it got it right.

Actually, why does "create PR" ask which repo to create it in, but "create issue" guesses based on context?

I'll add a decoration for it. We guess based on context because it seems likely that if you're creating an issue within VS Code you probably want to create an issue in the repo of the file you have open.

Hmm, if you create a lot of issues back to back a decoration won't work because we don't know when a tab is closed to remove the decoration properly. You can get an old decoration which is extremely confusing. I'll have to add a new line to the document for the repo.
