fix: Preserve new lines when buffering

[pmoncadaisla]

Instead of writing a println() which prints to stdout, write the new line character tot he io.Writer, this way it is preserved, otherwise, the character is lost.

This way, the code of tf-summarize can be used as a library inside your Go code rather than a executable binary and the expected output is the same.

Simple test code:

package main

import (
	"bytes"
	"os"

	"github.com/dineshba/tf-summarize/parser"
	"github.com/dineshba/tf-summarize/reader"
	"github.com/dineshba/tf-summarize/writer"
)

func main() {
	planOutputFile := "/tmp/plan"
	newReader, err := reader.CreateReader(os.Stdin, []string{planOutputFile})
	if err != nil {
		panic(err)
	}
	input, err := newReader.Read()
	newParser, err := parser.CreateParser(input, newReader.Name())
	terraformState, err := newParser.Parse()
	if err != nil {
		panic(err)
	}
	terraformState.FilterNoOpResources()
	newWriter := writer.CreateWriter(false, false, false, true, false, terraformState)

	var b bytes.Buffer
	newWriter.Write(&b)

	println(b.String())

}

Could you help in fixing the gosec failure https://github.com/dineshba/tf-summarize/actions/runs/5880538238/job/16355239558?pr=44#step:4:40 @pmoncadaisla
