Typo fix in NEWS.md (JuliaLang#38266)

There's also a bunch of issue links that are missing (JuliaLang#37410, JuliaLang#37247, JuliaLang#37540, JuliaLang#37973, JuliaLang#37461, JuliaLang#37753) but it seems there's a script that generates the links so I'm assuming that will be fixed automatically.
