Hello, this pull request changes the indentation level for Ruby language
from 2 spaces to the most used setting in the Ruby world: 2 spaces per
indentation level.
This setting is mentioned in the [Ruby style guide from the Rubocop
(Ruby linter and formatter)
team](https://rubystyle.guide/#spaces-indentation) and/or in another
popular Rubocop configuration tool -
[`standardrb`](https://github.com/standardrb/standard/blob/main/config/base.yml#L233)
Thanks!
