Fixes #10230.

This PR fixes a false positive for Lint/AmbiguousRange when a range is composed of some literals.
If it's just literals, it's clear even without parentheses, so this PR will accept them.


Before submitting the PR make sure the following are checked:

  • The PR relates to only one subject with a clear title and description in grammatically correct, complete sentences.
  • Wrote good commit messages.
  • Commit message starts with [Fix #issue-number] (if the related issue exists).
  • Feature branch is up-to-date with master (if not - rebase it).
  • Squashed related commits together.
  • Added tests.
  • Ran bundle exec rake default. It executes all tests and runs RuboCop on its own code.
  • Added an entry (file) to the changelog folder named {change_type}_{change_description}.md if the new code introduces user-observable changes. See changelog entry format for details.

Some literals == different literal types?

Fixes rubocop#10230.

This PR fixes a false positive for `Lint/AmbiguousRange`
when a range is composed of all literals except basic literals.
If it's just literals, it's clear even without parentheses,
so this PR will accept them.

I'm sorry for the confusion. Some literals meant all literals except basic literals. So, I think all literals (not only basic literals) will be in a clear (unambiguous) range.
