Show how to update the list of available Ruby versions

Browse source 
It wasn't clear how to update the list of installable Ruby versions after installing rbenv from Git. This is a bit confusing for people who use rbenv to run third party Ruby apps rather than write their own and are less likely to know/care about the distinction between `rbenv` and `ruby-build`. I hadn't touched it for about 2 years and totally forgot that I'd need to manually update ruby-build.

Alternatively, it might be better to make ruby-build a git submodule.

#### Updating the list of available Ruby versions
If you're using the `rbenv install` command, then the list of available Ruby versions is not automatically updated when pulling from the rbenv repo. To do this manually:
```sh
$ cd ~/.rbenv/plugins/ruby-build
$ git pull
```
