Upgrade Ruby installed by RVM

It’s easy to upgrade ruby installed by RVM. Only following several steps.

1. Upgrade RVM itself

At first, upgrade RVM to current stable ver.

/Users/yuichi% rvm get stable
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   185  100   185    0     0    431      0 --:--:-- --:--:-- --:--:--  1554

Upgrading the RVM installation in /Users/yuichi/.rvm/
    RVM PATH line found in /Users/yuichi/.bashrc.
    RVM sourcing line found in /Users/yuichi/.bash_login /Users/yuichi/.zshrc /Users/yuichi/.zlogin.

Upgrade Notes:

  * RVM comes with set of default gems including 'bundler', 'rake', 'rubygems-bundler' and 'rvm' gems,
    if you do not wish to get this gems install RVM with this flag: --without-gems="rvm rubygems-bundler"
    this option is remembered, it's enough to use it once.

  * If you wish to get more default(global) gems installed, install RVM with this flag: --with-gems="pry vagrant"
    this option is remembered, it's enough to use it once.

  * For first installed ruby RVM will: display rvm requirements, set it as default and use it.
    To avoid this behavior either use full path to rvm binary or prefix it with `command `.

  * Binary rubies are installed by default if available, you can read about it in help:
      rvm help install
      rvm help mount

  * The default umask for multi-user installation got extended to `umask u=rwx,g=rwx,o=rx`,
    comment it out to avoid automatic updates.
