* Fix artichoke-dev installer

* Add TruffleRuby 20.1.0

ruby-build 20200518

* ruby-build: add short option "-d" alias to "--definitions"

* rbenv-install: show the short list by default

  As suggested by @eregon, now we have "-l/--list" option for the short
  list of versions. Behaviour of `ruby-build --definitions` is kept as
  before for compatibility.

  rbenv-install:
    -L/--list-all       full list
    -l/--list           short list

  ruby-build:
    -d/--definitions    full list
    -l/--list           short list

  The short list now shows only latest stable versions
  for each Ruby implementations like the following:

      2.5.8
      2.6.6
      2.7.1
      jruby-9.2.11.1
      maglev-1.0.0
      mruby-2.1.0
      rbx-4.15
      truffleruby-20.0.0
