This cop enforces the use of $stdout/$stderr/$stdin instead of STDOUT/STDERR/STDIN.

https://rubystyle.guide/#global-stdout

# bad
STDOUT.puts('hello')

hash = { out: STDOUT, key: value }

def m(out = STDOUT)
  out.puts('hello')
end

# good
$stdout.puts('hello')

hash = { out: $stdout, key: value }

def m(out = $stdout)
  out.puts('hello')
end
