GH-329: [Website] Add a link to the Ruby End-Of-Life (EOL) schedule in the Prerequisites section of README.md (#330)
# Overview
This pull request adds a link to the [Ruby End-Of-Life (EOL)
schedule](https://www.ruby-lang.org/en/downloads/branches/) to the
[Prerequisites section of the `README.md` for
`apache/arrow-site`](https://github.com/apache/arrow-site#prerequisites).
It also spells out the acronym EOL as End-Of-Life to avoid any
confusion.
