Remove unnecessary constants

[ydah]

Perhaps, but it appears to be a constant that is not used now.

Before submitting the PR make sure the following are checked:

• Feature branch is up-to-date with master (if not - rebase it).
• Squashed related commits together.
• [-] Added tests.
• [-] Updated documentation.
• [-] Added an entry to the CHANGELOG.md if the new code introduces user-observable changes.
• The build (bundle exec rake) passes (be sure to run this locally, since it may produce updated documentation that you will need to commit).

Where do they come from? I found the same constant mentioned in rubocop, but didn’t find out why.

I found SUPPORTED_STYLES mentioned in rubocop/rubocop#693, but only in specs 🤷🏼
