docs(issue-template): ask for package manager and version (#4867)

Package manager and install mode — especially Yarn Plug'n'Play vs a
node_modules linker — frequently determine module-resolution behavior,
but the bug template only collected commitlint/git/node versions. Add a
required free-text field so reporters state their package manager and
version (and, ideally, the install mode).
