Incorrect SimpleCov.formatter usage example in documentation

[bestwebua]

Following to the code under the hood:

simplecov/lib/simplecov/configuration.rb

Lines 110 to 112 in 9036554

	def formatters=(formatters)
	@formatter = SimpleCov::Formatter::MultiFormatter.new(formatters)
	end

For SimpleCov.formatters call examples in the current documentation we need to use array of formatters:

SimpleCov.formatters = [
  SimpleCov::Formatter::HTMLFormatter,
  SimpleCov::Formatter::CSVFormatter,
]

instead of instance of SimpleCov::Formatter::MultiFormatter:

SimpleCov.formatters = SimpleCov::Formatter::MultiFormatter.new([
  SimpleCov::Formatter::HTMLFormatter,
  SimpleCov::Formatter::CSVFormatter,
])
