[nanobox] Minor tweaks for 1.5 (#4395)

- Be less strict about the Ruby version, which resolves a build failure.
- Add libidn as a dependency (until Nanobox adds idn-ruby to the list of gems with a dependency on it).
- Remove redundant bundler commands (Nanobox's Ruby engine handles these things cleanly on its own, now).
