Update .rubocop.yml

[manicmaniac]

Problem

.rubocop.yml seems outdated and it says like the following error messages when you run bundle exec rake rubocop just after cloned repository then ran ./configure.

Running RuboCop...
.rubocop.yml: Metrics/LineLength has the wrong namespace - should be Layout
.rubocop.yml: Style/FileName has the wrong namespace - should be Naming

RuboCop failed!

Solution

• Update .rubocop.yml to resolve those warnings and errors
• Update supported Ruby versions because the current version of RuboCop doesn't support Ruby less than 2.5.
• Run bundle exec rubocop -A to solve linter warnings
  • Potentially rubocop -A might change the semantics but I confirmed all changes are valid
  • I also confirmed all linter warnings have gone after running rubocop -A
