Fix "reports export failures" test on Logs SDK

[kaylareopelle]

The following test is failing intermittently on MacOS:

opentelemetry-ruby/logs_sdk/test/opentelemetry/sdk/logs/export/batch_log_record_processor_test.rb

Lines 474 to 493 in 60ebfd4

	it 'reports export failures' do
	# This test is unreliable on Windows platforms, but works just fine on others
	skip if Gem.win_platform?
	# skip the work method's behavior, we rely on shutdown to get us to the failures
	processor.stub(:work, nil) do
	mock_logger = Minitest::Mock.new
	mock_logger.expect(:error, nil, [/Unable to export/])
	mock_logger.expect(:error, nil, [/Result code: 1/])
	mock_logger.expect(:error, nil, [/unexpected error in .*\#export_batch/])
	OpenTelemetry.stub(:logger, mock_logger) do
	log_records = [TestLogRecord.new, TestLogRecord.new, TestLogRecord.new, TestLogRecord.new]
	log_records.each { |log_record| processor.on_emit(log_record, mock_context) }
	processor.shutdown
	end
	mock_logger.verify
	end
	end

Previously, it was disabled for only Windows environments. PR #2026 will update the test to run only locally until we can resolve this issue.
