Pattern: Malformed heredoc indentation
Issue: -
This rule checks the indentation of the here document bodies. The bodies
are indented one step.
In Ruby 2.3 or newer, squiggly heredocs (<<~) should be used. If you
use the older rubies, you should introduce some library to your project
(e.g. ActiveSupport, Powerpack or Unindent).

RUBY| Attribute | Value |
|---|---|
| EnforcedStyle | auto_detection |
| SupportedStyles | auto_detection, squiggly, active_support, powerpack, unindent |
